Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To notify the decrease of remaining developer and an empty state as soon as possible by extending a developer supplying operation or by enabling recognition of a timing to interrupt printing. SOLUTION: If a toner amount and/or a toner concentration in a developer vessel is not appropriate (S501), after having executed an initial setting of a rotation time (S502), a toner supply of the predetermined amount is executed (S503), an addition calculation of the rotation time of a toner supplying roller (S504) and a calculation of the integrated rotation time (S505) are executed. When the toner amount and/or the toner concentration at the step S506 become appropriate, detection of the near-end of the toner is executed from the integrated rotation time (S508), and when the toner amount does not become appropriate, an empty detection is executed (S510) after confirming whether the pre-determined rotation time is exceeded.  By this processing, the near-end notice can be executed before the empty notice, and further by executing the empty detection at a short interval, a trouble to give the empty notice after a long supplying operation can be dissolved.

Filed: 1989-06-14
Abstract: PURPOSE:To improve the operability of a file system by deciding whether a file to be transcribed can be totally transcribed to a storage area, i.e., the transcribing destination in accordance with the size information added to the attribute information. CONSTITUTION:A CPU 10 stores a file system, in which a file of the transcribing destination serves as a part of constitution, into a real memory 16 from a file server 22 via an Ethernet control part 19. When a transcription operating request is received, the CPU 10 discontinues the transcribing operation as long as the shortage of the memory capacity is decided for the transcribing destination. If the sufficient memory capacity is confirmed, a file to be transcribed is totally transcribed to a directory file of the transcribing destination. Then the value of a partial tree size showing the memory capacity of a file smaller than the working directory file included in the attribute of the directory file is rewritten into the value added with the stored file size. At the same time, a transcribing operation is carried out for addition of the information on the transcribed file name. Then a operation is through.
