Exhibit  10.23 -  Lease  Guarantee  Agreement  dated July 23, 2004

MASTER  LEASE AGREEMENT NUMBER 4406
LESSEE: QUINTEK TECHNOLOGIES, INC.

                       CONTINUING EQUIPMENT LEASE GUARANTY

                                   INDIVIDUAL

The above-referenced  lessee (the "Lessee") has requested that VENCORE SOLUTIONS
LLC (the "Lessor") lease certain equipment (the "Equipment") to Lessee under the
above-referenced Master Lease Agreement.  Lessor and Lessee intend to enter into
one or more Lease  Schedules,  which shall  incorporate  any Master  Lease Terms
Addenda attached thereto (the "Leases") under the Master Lease Agreement.

As Guarantor,  I acknowledge  that I have read and  understand  the Master Lease
Agreement,  and that I understand that my obligations under this Guaranty extend
to each and every one of the Leases entered into between Lessor and Lessee.

For good and  valuable  consideration,  I, as primary  obligor,  absolutely  and
unconditionally  guarantee full performance by Lessee, when due, all of Lessee's
present and future  obligations  under the Leases.  In the event that any amount
remains  due,  owing and unpaid by Lessee  under the Leases,  or becomes due and
owing  under  the  Leases  as  a  result  of   acceleration   or  otherwise,   I
unconditionally  promise to pay Lessor those  amounts up to a maximum  amount of
Two Hundred Forty Thousand Dollars and 00/100 ($240,000.00).  I acknowledge that
Lessor has made no representations to me as to the creditworthiness of Lessee. I
waive any right to require  Lessor to enter into the  Leases  with  Lessee or to
otherwise extend credit to Lessee.

My liability is limited to a maximum  amount of  $240,000.00  and my obligations
are continuing until Lessee has made a minimum of Twelve (12) rental payments as
agreed on all Lease Schedules in accordance with the terms and conditions of the
lease  agreement.  This Guaranty will bind my estate as to indebtedness  created
both  before and after my death or  incapacity  regardless  of  Lessor's  actual
notice of my death or  incapacity.  This  Guaranty will remain in full force and
Lessor may rely on it, until I deliver to Lessor written notice of  termination.
The  termination  will  not  affect  any of the  liabilities  existing  prior to
Lessor's receipt of the notice.

Fluctuations  may occur in the  aggregate  amount  of my  liability  under  this
Guaranty.  Lessor may enter into additional Leases with Lessee without notice to
me.  I have  established  adequate  means  of  obtaining  information  regarding
Lessee's  financial  condition on a continuing basis. I agree to keep adequately
informed of all facts, events, or circumstances  relating to Lessee, which might
in  any  way  affect  my  risks  under  this  Guaranty.  Absent  a  request  for
information,  Lessor has no  obligation  to  disclose to me any  information  or
documents  acquired by Lessor in the course of its relationship with Lessee. The
reduction  in the amount of my  liability  under this  Guaranty,  even to no/100
dollars ($0.00), will not terminate this Guaranty.

I have an interest, financial or otherwise, in Lessee. Lessee and I will benefit
from the lease of the Equipment.  This Guaranty is executed at Lessee's request.
I give this Guaranty to secure all of Lessee's obligations under the Leases, and
to induce  Lessor to lease the  Equipment  to Lessee.  Lessor  will rely on this
Guaranty when entering the Leases.  My obligations to Lessor are  independent of
the  obligations  of Lessee  under the Leases,  and  separate  claim may be made
against  me even if a claim  is not made  against  Lessee.  Lessor  and / or its
assigns may at any time  investigate  my  creditworthiness  using all  available
means.

                                       1

I WAIVE (1) ANY RIGHT TO REQUIRE LESSOR TO PURSUE A PARTICULAR  REMEDY,  AND THE
BENEFIT OF ANY "ONE ACTION" OR  "ANTI-DEFICIENCY"  LAWS AND OTHER LAWS WHICH MAY
PREVENT LESSOR FROM BRINGING AN ACTION, INCLUDING A CLAIM FOR DEFICIENCY, BEFORE
OR AFTER LESSOR'S  COMMENCEMENT OR COMPLETION OF ANY TYPE OF FORECLOSURE ACTION;
(2) NOTICE OR  PRESENTMENT;  (3) ANY CLAIMS ARISING OUT OF LESSOR'S  ELECTION OF
REMEDIES  THAT MAY  AFFECT  MY  RIGHT  OF  REIMBURSEMENT  FROM  LESSEE;  (4) ANY
DISABILITY OR DEFENSE OF LESSEE;  (5) THE BENEFIT OF ANY STATUTE OF LIMITATIONS;
AND (6) ANY DEFENSES  GIVEN TO  GUARANTORS AT LAW OR IN EQUITY OTHER THAN ACTUAL
PAYMENT.

IF LESSEE IS OR BECOMES  INSOLVENT,  I RELINQUISH  IN FAVOR OF LESSOR AND LESSEE
ANY  CLAIM OR RIGHT TO  PAYMENT  I MAY NOW  HAVE OR  SUBSEQUENTLY  HAVE  AGAINST
LESSEE,  BY  SUBROGATION  OR  OTHERWISE,  SO  THAT I WILL  NOT AT ANY  TIME BE A
CREDITOR OF LESSEE AS  CONTEMPLATED  BY 11 USC  SECTION  547(b).  REGARDLESS  OF
WHETHER LESSEE BECOMES  INSOLVENT,  I AGREE THAT LESSEE'S  OBLIGATIONS UNDER THE
LEASES  WILL BE PRIOR TO ANY CLAIM  THAT I MAY HAVE  AGAINST  LESSEE OR  ANOTHER
GUARANTOR.  I  EXPRESSLY  SUBORDINATE  ANY  CLAIM I MAY HAVE  AGAINST  LESSEE OR
ANOTHER  GUARANTOR  TO ANY CLAIM  LESSOR  MAY HAVE  AGAINST  LESSEE  OR  ANOTHER
GUARANTOR.

I  authorize  Lessor  from time to time to  compromise,  renew,  alter,  extend,
accelerate,  or otherwise change the terms of the Leases. Lessor may assign this
Guaranty  in whole or in part.  I will not  dispose of  substantially  all of my
assets without  Lessor's written  consent.  If more than one guarantor  executes
this Guaranty,  our obligations  under this Guaranty are joint and several,  and
Lessor may deal with any of us in any manner it chooses. This Guaranty will bind
my successors and assigns,  and will inure to the benefit of Lessor's successors
and assigns.  I waive  notice of  assignment.  I will not assign my  obligations
under this Guaranty  without prior  written  consent from Lessor.  To the extent
that the Leases and other related  documents  were signed prior to the execution
of this Guaranty,  their  execution  contemplated  this  Guaranty.  In the event
Lessor sues to enforce this Guaranty,  the prevailing  party will be entitled to
recover a  reasonable  sum for legal fees and  expenses  with or  without  trial
and/or on appeal, together with all sums allowed by law.

The singular used in this Guaranty includes the plural,  and the plural includes
the  singular.  References  to  the  masculine,  feminine  and  the  neuter  are
interchangeable, as the context requires.

THIS  GUARANTY HAS BEEN  DELIVERED TO LESSOR AND IF ACCEPTED WILL BE ACCEPTED BY
LESSOR IN THE STATE OF OREGON AND WILL BE CONSTRUED  UNDER OREGON LAWS.  ANY AND
ALL  SUITS OR  ACTIONS  TO  ENFORCE  THIS  GUARANTY  OR FOR ITS  BREACH  MUST BE
INSTITUTED  AND  MAINTAINED  IN  MULTNOMAH  COUNTY,  OREGON.  At  lessor's  sole
discretion,  any suit or other  action may also be brought in any other court in
the state of lessee's principal business location.  i hereby waive any objection
relating to improper venue or forum non-conveniens.  i expressly waive any right
to trial by jury so that trial shall be by and only to the court.

If the court finds any  provision of this  Guaranty  unenforceable,  the finding
will  not  make  the  provision   unenforceable  as  to  any  other  persons  or
circumstances,   and  all  of  the  other   provisions  will  remain  valid  and
enforceable.  I consent  to the use of  original  or  facsimile  copies of Lease
Schedules,  along with an  original,  facsimile or photocopy of the Master Lease
Agreement, and facsimile or photocopies of the related documents (including this
Guaranty),  for  all  purposes,  including  but  not  limited  to,  evidence  in
litigation or any other judicial proceeding.
