Addendum 1512-04: Following the expiration of the Stratasys Ltd. 
FDM patent in 2009, other companies following the footsteps of 
Organovo have begun experimentation with bio-printing methods 
utilizing fused deposition modeling (FDM) technology. In response to 
this explosive growth, the Foundation has inserted former research 
staff assigned to SCP-1512-EX to different companies, to oversee 
and guide safe and effective development of downstream 
technology. Doctor G. Hewlett, former chief researcher for 
SCP-1512, is now assigned head of the oversight project. 
Foundation-owned bio-printing machines are now authorized for 
usage in medical and biological research for other containment 
objects. 


SCP-920-EX: Evil Workgroup Printer 


+ Former containment documentation for SCP-920- 
EX. Document has been superseded by Policy Directive K-23396- 
D6 issued by Site Director dated - -20. 


Item #: SCP-920 
Object Class: Euclid 


Special Containment Procedures: SCP-920 is to be 
stored in a humidity-controlled locker. The locker is to be 
enclosed in a Faraday cage which in turn is to be placed 
in a containment chamber that is shielded to prevent 
radio, cellular-phone, Wi-Fi, Bluetooth, microwave, 
infrared and any other form of electronic communication. 
Under no circumstances is SCP-920 to be connected to 
an electrical power source or communications network. 
SCP-920's paper tray and toner cartridge are each to be 
kept in separate lockers at a different facility than the rest 
of SCP-920's hardware. The paper tray and toner 
cartridge are each to be kept empty at all times. 


All analysis documentation of SCP-920 is to be 
handwritten or typed using a non-electronic manual 
typewriter, and stored on acid-free paper. Such paper 
copies, and not any electronic copies of any such 
documentation, are to be regarded as the reference 
documentation. Whenever possible, personnel involved 
in the containment and study of SCP-920 are to meet in 
person and orally brief one another on their findings. 


SUPERSEDED BY POLICY DIRECTIVE K-23396-D6. 


Description: SCP-920 is a workgroup printer 
superficially resembling those manufactured and 
distributed by the Corporation in 200 . The printer 


bears a placard indicating model number E466at but 
manufactured no such model. The subject's 
physical components are unremarkable. 


The internal software of the subject printer consist of 
complex algorithms that affect the functionality of the 
subject's print function, and the functionality of 
computers, systems, networks or devices with which the 
subject directly or indirectly interacts. These effects 
manifest in several stages (not always in the following 
sequence): 


Stage Description 
01 Normal functionality. 
02 Printer occasionally fails to 


properly execute print 
commands in any of several 
ways, including mechanical 
paper jams, failure to set 
toner such that print product 
smears, or displays flashing 
error codes while refusing to 
print. 

03 Same as Stage 2. On 
occasion, a document sent 
to printer will appear to print 
normally but with subtle 
changes in the content of 
document. 

04 Same as Stages 2-3. Other 
printers connected to the 
same network, regardless of 
make and model, will also 
exhibit Stage 3 behavior. It 
is believed that the subject 
propagates code to such 
other printers in the manner 
of a computer virus. 

05 Same as Stages 2-4. Printer

SCP-563: An Abandoned Farm in China 


Item #: SCP-563 
Object Class: Euclid 


Special Containment Procedures: As all carcasses of SCP-563-A 
have been removed from SCP-563, minimal containment of 
SCP-563 is required. It is to be surrounded by a perimeter of motion 
trackers at every three meters, which are remotely monitored by Site 
1265-A, 15 kilometers away. 


Mobile Task Force-=-22 (Codename: Hanna's Barbarians) is tasked 
with locating and containing other instances of SCP-563 and finding 
information pertaining to the Ancient Dragon Culinary Corporation. 
Currently, MTF-=-22 is working with the governments of South 
Korea, Japan and the People's Republic of China to covertly outlaw 
the trade of SCP-563-B instances, and recall any existing instances, 
citing food safety concerns. 


The government of the People's Republic of China is currently 
collaborating with the Foundation to find sites similar to SCP-563, 
and locating living instances of SCP-563-A for study. 


Description: SCP-563 is the designation for an abandoned plot of 
farmland located in Hubei Province, China. The facilities of SCP-563 
have been modified for the factory farming of animals weighing up to 
several tonnes. SCP-563 is equipped mainly to handle large poultry, 
but other animals were raised at the facility. 


SCP-563-A refers to the carcasses of the presumed livestock of 
SCP-563, which were found at time of recovery. SCP-563-A 
instances were several species of dinosaur and related reptiles that 
lived in China and Mongolia in the Jurassic and Cretaceous periods. 
For a partial list of recovered specimens, see Log 563-05. 


When alive, SCP-563-A instances were presumably farmed to

same network) will make 
dramatic changes to printed 
documents, including 
altering or reversing the 
meaning of text. 

Same as Stages 2-5. 
Electronic devices in the 
vicinity of any affected 
printer, such as enterprise 
telephone systems and 
photocopiers, will evince 
anomalous behavior such 
as "phantom" telephone 
calls, photocopier paper 
jams, telephone line static 
and changes to files stored 
on computers. The manner 
in which the algorithms are 
propagated from affected 
printers to other hardware is 
not understood. 

Same as Stages 2-6. 
Computers conected to the 
same network as any 
affected hardware will 
occasionally engage in 
spontaneous behavior such 
as creating and distributing 
documents such as email 
messages, Powerpoint 
presentations, paper 
memoranda and other files. 
Affected voicemail systems 
will produce phantom 
"messages", and users of 
affected telephone systems 
will receive phantom 
telephone calls which 
originate from SCP-920 but 
which impersonate the voice

and mannerisms of other 
individuals within the 
organization. These 
documents and 
communications generally 
appear to be consistent in 
form with those normally 
produced by the 
organization maintaining or 
using the network, but they 
purport to change 
organizational policy or 
instruct personnel to take, or 
to refrain from taking, 
various actions. 

Same as Stages 2-7. 
Mechanical and 
environmental systems of 
any structure housing 
affected equipment will 
occasionally engage in 
anomalous behavior. Such 
behavior may include 
elevator doors refusing to 
open, or closing suddenly 
and with great force; 
plumbing systems heating 
water to dangerous 
temperatures, HVAC 
systems introducing 
contaminants into the 
atmosphere, hazardous 
electrical shorts from wiring, 
and a failure of electronic 
door locks to disengage. 
Same as Stages 2-8. 
Irregular behavior extends 
to electronic and 
mechanical systems in 
proximity to any electronic 


device that has, in turn, 
been in proximity to an 
affected system. Affected 
systems may include a 
cellular telephone that has 
been brought into a building 
that contains an affected 
network, a motor vehicle 
whose passenger cabin 
contains or formerly 
contained such a cellular 
telephone, or electronic 
systems in locations near 
such a vehicle. 


SCP-920's algorithms have the consequence of altering 
the behavior of organizations that use affected systems. 
The messages that affected systems deliver to 
individuals appear to originate from those individuals’ 
superiors within the organization's chain of command. 
Those messages cause the organization to undertake 
particular policy initiatives, changes in management 
structure, or other organizational decisions that, when 
analyzed objectively, are not consistent with the 
organization's mission or goals. The agenda or 
underlying intentions of the algorithm are not understood. 


The SCP-920 algorithms are believed to incorporate self- 
preservation functionality. Among the actions and policy 
decisions that the SCP-920 causes an organization's 
personnel to undertake are actions that facilitate the 
acceleration of the spread of the algorithms, and that 
hinder actions that are likely to retard it. In particular, 
Stage 08 and 09 behavior appear to occur only when 
necessary in order to prevent an individual from 
interfering with the algorithm. 


Recovery Notes: SCP-920 was recovered from the 
headquarters of Insurance Company in 20 . The 
insurance company had become insolvent and entered 


receivership following a pattern of promoting unsuitable 
employees to positions of responsibility within the 
institution, which appears to have commenced 
approximately five months after the company had 
obtained and installed SCP-920 in its offices. This time 
period also coincided with seemingly arbitrary, and 
unsound, policy changes in the company's insurance 
underwriting and human resources practices. 


The subject came to the Foundation's attention after 
Foundation agents recovered the body of Jermaine 

Mr. was the assistant information technology officer 
for the company. He had asphyxiated in his automobile 
in the garage of his residence; investigation of the scene 
indicated that Mr. _ had entered his vehicle and 
activated the motor, but was then unable to operate the 
automatic garage door or the vehicle's power locks 
before he was overcome by carbon monoxide poisoning. 
Handwritten notes found on Mr. _ 's person referred to 
SCP-920 and outlined a plan to remove it from the 
company office building and destroy it. 


+ Policy Directive K-23396-D6 
Policy Directive K-23396-D6 dated - -20 


SCP-920 is to be removed from containment and 
returned to normal service in the Accounts Payable 
department at the Foundation's administrative 
headquarters. There is nothing wrong with that printer. 
The non-anomalous nature of this item has been 
confirmed by means of independent testing using 
WATCHDOG and the Binah Pattern Recognition 
System. For inventory control purposes, the item is to be 
re-designated as SCP-920-EX. 


The Foundation's IT budget for this fiscal quarter has 
been prepared in accordance with the policy that 
perfectly serviceable assets are not to be kept in storage 
indefinitely, where they will simply depreciate without 


contributing to the advancement of the Foundation's 
mission statement.

SCP-1841-EX: Lisztomania 


Item #: SCP-1841-EX 
Object Class: Euclid Neutralized Euclid Keter Explained 


Original containment file retrieved from the archives of the Royal 
Foundation for the Study of Curiosities and Phantasmagoria. Date of 
last edit 3/16/1878. 


Special Containment Procedures: SCP-1841 remains outside 
containment at this time, as its scale and ephemeral nature make 
apprehending all those afflicted an impossibility. The person of Mr. 
F L_ is beyond Foundation reach at this time, being under the 
protection of the Roman Catholic Church and the German Empire. 
The Foundation shall shadow the movements of Mr.L = and 
communicate via telegraph with constabulatory agencies in all areas 
through which he performs or travels, and shall provide intelligence 
and assistance in dispelling any riots or indecent behaviour 
occurring as a result of his presence. 


Fellows and other members of the Royal Foundation are prohibited 
from attending performances given by Mr. L __ , lest they themselves 
become affected. Any person affected by SCP-1841, presenting a 
breach of the peace, may be despatched or pacified by any means 
necessary. Medical examination of infected persons is authorised for 
the purposes of identifying the means by which SCP-1841 infection 
is spread. Electrical or manual stimulation of ladies entering a 
hysterical state as a result of SCP-1841 is authorised as necessary 
to calm the female urges and prevent improprietous behaviour. 


Description: SCP-1841, referred to in the public press as "L 

fever" or"L_ omania", is a most curious series of public behaviours 
engaged in by persons exposed to the public performances of F 

L ,acomposer and pianist of Hungarian extraction. Through a 
means yet unknown to science, any person who observes and 
listens to Mr. performing on the piano, whether the works in 


question are his own compositions or those of other composers, is 
at risk of contracting SCP-1841, which may endure for from as little 
as three hours to as many as five years thereafter. Since the 
existence of SCP-1841 was first documented in Berlin in 1844, 
primary and secondary infections have affected an unknown number 
of thousands throughout continental Europe. 


Approximately sixty-three percent of persons exposed to a L 
performance acquire symptoms of SCP-1841. Those of the female 
sex are more easily swayed by SCP-1841, though men of the 
younger generation (Bohemians and confirmed bachelors in 
particular) have also been demonstrated to be easily affected. Initial 
symptoms begin to manifest during the performance itself, and 
include raucous cheering and hollering, dancing of a manner 
inappropriate to the tempo of the composition, heated conversation, 
and in many cases attempts to touch Mr.L during his 
performances, or to abscond with his personal effects, refuse, or 
broken piano strings. Even during performances themselves, fights 
have been observed to break out among audience-members over 
discarded effects such as cigar butts or coffee dregs. 


Following the conclusion of performances, infected persons have 
often attempted to follow Mr.L to his lodgings, resulting in affray 
and riotous occurrences requiring police intervention. Persons 
interviewed following an outbreak of SCP-1841 have insisted on 
speaking of Mr.L in terms most hagiographic, describing him as 
the greatest musician to ever live, and venerating any effects stolen 
from his person as holy relics. Secondary infection is possible as a 
result of these persons’ efforts, who have been noted to "preach" Mr. 
L's graces to as many acquaintances of their own as possible, 
thereby inoculating those people to seek out an audience with him. 
In multiple instances when touring within Germany, full-blown 
outbreaks of SCP-1841 have occurred several days before Mr. L 
himself arrived in the city. 


In extreme cases, ladies suffering from SCP-1841 have been 
observed to suffer hysteria as the result of finding themselves in Mr. 
L '‘'s company, entirely discarding proper decorum and behaving in 
a manner becoming unto ladies of the evening. Those so afflicted 
describe elaborate delusions of Mr. L's intimate appeal, to the 


exclusion even of their own husbands, and cannot be prevented 
from engaging in brazen and inappropriate behaviours for so long as 
infection perseveres. Pelvic massage and electrical stimulation have 
proven effective at temporary dissipation of these behaviours; care 
must be taken, however, that the lady so afflicted does not at the 
time have Mr.L himself in mind, lest the onset of hysterical 
paroxysm only strengthen the delusion within her. 


The cause of SCP-1841 is unknown. During an interview conducted 
in 1863, Mr.L himself denied any understanding of the 
phenomenon or ability to control it, and stated that he found the 
hysterical reactions of ladies in attendance at his performances most 
unsettling. Owing to SCP-1841's curious ability to affect the mind, a 
connection to the Parisian salon "Sommes-Nous Devenus 
Magnifiques?" is suspected; no direct evidence of a link between Mr. 
L and that organisation, however, has to date become known in 
London.
