CAUTION
This product is a class 1 laser product that complies with 21CFR 1040 of the CDRH
standard and IEC825. This means that this machine does not produce hazardous laser
radiation. The use of controls, adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
This laser radiation is not a danger to the skin, but when an exact focusing of the
laser beam is achieved on the eye’s retina, there is the danger of spot damage to the
The following cautions must be observed to avoid exposure of the laser beam to your
eyes at the time of servicing.
When a problem in the laser optical unit has occurred, the whole optical unit must
1)
be exchanged as a unit, not as individual parts.
Do not look into the machine with the main switch turned on after removing the
2)
developer unit, toner cartridge, and drum cartridge.
Do not look into the laser beam exposure slit of the laser optical unit with the
3)
connector connected when removing and installing the optical system.
The middle frame contains the safety interlock switch.
4)
Do not defeat the safety interlock by inserting wedges or other items into the
switch slot.

[Paper Transport Section]
Outline
The paper transport section serves the function of transferring paper from each
paper feed port to the registration roller section.
Paper from manual feed, paper feed tray units 1 and 2 (optional), and the right
paper feed tray of the paper feed tray units 1 and 2 is transported horizontally,
whereas paper from the left paper feed tray of the paper feed tray units 1 and 2,
paper feed tray 3 and paper feed tray 4 is transported vertically to the registration
roller section.
After the leading edge of the paper is synchronized with the leading edge of the
drum image in the registration roller section, the paper that is transfer printed with
the image in the transfer section passes through the fusing section and is discharged either face-down or face-up.

5. Scanner section
A. General
There are following three methods of scanning documents in this machine.
a. Place a document on the table glass. The copy lamp unit is operated to radiate
copy lamp light onto the document, scanning the document with the CCD.
b. The SPF feeds a document. The copy lamp light is radiated onto the document
which is stopped at the specified position and the document is scanned by the
CCD.
c. The SPF feed a document. The LED light of the CIS unit which is attached to
the SPF is radiated to the back of the document, and the document is scanned
by the CIS.

[3] SETTING AND ADJUSTMENTS
Each adjustment item in the adjustment item list is associated with a specific JOB
number. Perform the adjustment procedures in the sequence of Job numbers
from the smallest to the greatest.
However, there is no need to perform all the adjustment items. Perform only the
necessary adjustments according to the need.
Unnecessary adjustments can be omitted. Even in this case, however, the
sequence from the smallest to the greatest JOB number must be observed.
If the above precaution should be neglected, the adjustment would not complete
normally or trouble may occur.

This adjustment is needed in the following situations:
• The high voltage power PWB (MC/DV/TC) has been replaced.
• U2 trouble has occurred.
• The PCU PWB has been replaced.
• The EEPROM of the PCU PWB has been replaced.

plate simultaneously, the parallelism of Scanner Unit B is proper.

unit drive pulley to change the parallelism of Scanner Units A and B. (Change
the positional relationship between the scanner unit drive pulley and the drive
shaft.)
6) Tighten the scanner unit drive pulley fixing screw.
