CONCERNING AN UPGRADE IN ROM.
1.Model Name: SF-2035/1025
2.General: For the reasons listed below , there may be leaks of static electricity in the machine. As
a result of such leaks, the IC (ROM) in the main PWB may malfunction so that the copy
count does not cycle properly. The new ROM should eliminate this problem.
(Cause of problem)
Inadequate grounding of electricity may result if the unit is cleaned improperly, if
maintenance is carried out while the power is on, or if the unit and its pedestal are not
screwed together correctly.
3.Description: (1) In the old version, counter data was backed up when the power was turned off. The
new version of the ROM is designed to back up counter data at the completion of each
copying job. Since the software for the IC (ROM) of the main PWB has therefore been
changed, the part codes have changed as well.
This change is effective as of May, 1995 production for most models, but other changes
were carried out for the SF-2035 previously. This report covers both sets of changes.

Type of change Notes
1. Eliminates the problem of the machine resetting itself when
malfunctions of the main motor lock(L4-01) occurred
2. When storage auditor mode was selected, if malfunctions occurred
in the number input mode (when the main unit is “not ready”), the error
codes were not displayed. This new version eliminates that problem.
1. The timing in which backing up of counter data occurs has changed.
(From occurring during power-down to occurring as each job is
completed.)
