SHARP SP1655 Technical Report

Date: Jan. 10, 1994

OPTION : SF-S53

CHANGE IN SOFTWARE FOR MODEL SF-S53.

1. PREVENTION OF DIAGONAL PAPER OUTPUT FOR A4R (LETTER R) SIZE COPY PAPER.

2. PREVENTION OF SELECTION ARM MALFUNCTIONS DURING THE MANUAL STAPLE
COPY MODE.

3. PREVENTION OF F1-00 ERRORS OCCURRING DURING OPENING AND CLOSING OF THE
DOOR ON THE SORTER SIDE OF THE MACHNIE.

No. : SP-1655

1.General: Correction of the trouble described below has been carried out for model SF-S53 by
changing the software used in the machine.

2.Problem: 1. Diagonal paper output of A4 R (Letter R) copy paper caused by selection errors

sometimes occurs during sort mode copy operations.

2. Selection arm malfunctions sometimes occur during manual staple mode copy

operations.

➀ If non-sort mode copy operations (example: A4 R size copy paper) are carried out

without removing the copy paper from the bin after sort mode copy operations
(example: A4 size copy paper), and then after completion manual staple mode copy
operations are carried out, the selection arm moves to the non-sort mode copy
paper size (example: A4 R size) position, pressing down on the sort mode copy
paper (example: A4 size).

➁ The same problem occurs after the interrupt key is depressed and non-sort copy

operations are carried out after sort copy operations.

3 Prevention of F1-00 errors from occurring during opening and closing of the door on

the sorter side of the machine.

3.Cause: 1. Variations in copy paper output volume are such that when there is a large volume of

copy paper output, the selection arm moves while the copy paper is still returning to
the rear edge of the bin. This causes the copy paper to gather on one side, causing
diagonal copy paper output.

2. Paper size selection data was rewritten during non-sort copy operations.
3-1. When used with the SD-2060 model.

• The initialization of the conveyor motor is stopped by the opening of the door.
When the door is then closed the sorter reinitializes itself. As a result when the main
power of the machine is turned on and the door switch of the sorter switches back
and forth between on and off, the machine continues operations without giving
transmission permission for the sorter transmission request, and when the sorter
gives the transmission command an “F1-00" error occurs.

3-2. When used with the SF-2035 model.

• When the sorter door is opened during conveyor motor initialization, the sorter is
busy with the initialization process.

When a command from the machine is continually received during this condition, the
command buffer becomes full, and an ”F1 - 00" error occurs.

4.Description: 1. The software has been changed to slow the output speed to 70 mm / sec less than
the current speed. When copy paper is output, the flight of the copy paper into the bin is
more controlled, so that each page completely returns to the rear end of the bin before
the next page is output.

2. The software has been changed so that the paper size selection data is not rewritten
during non-sort copy operations.

3-1. The software has been changed so that when the sorter door is closed, the sorter

does not reinitialize itself. Instead the machine sends a reinitialization command to
the sorter, and initialization of the conveyor motor is carried out by a pin home
position command.

3-2. The software has been changed so that when the sorter door is opened during the

conveyor motor initialization process, the initializat ion process is terminated at its
midway stage.

To carry out the above software changes, the sorter control PWB parts have been
changed as follows.

Parts name. Old. New. Version.

0GZFM60105050 0GZFM60105060 200 V series.

The information given by the ROM label has also been changed in accordance with the
above.
