4.2.3 Removing the Circuit Board Tray

Since the B101 MAIN and B101 PSB/PSE boards are built in a removable tray, remove the
whole tray as described below to access these boards. Keep in mine that for many service
operations you do not have to fully remove the tray, you can just pull it out far enough to
remove the connectors.
1. Remove the rear cover and upper cover as described in "Rear cover" on page 91 and
"Upper cover" on page 92.
2. As shown below, remove the three screws (CBS 3x6) on the back of the tray and one
screw on each side. (To remove the screw on the carriage-motor side, it is
recommended you first remove the hand hold as this partially blocks access to the
screw.)
Total of five CBS 3x6 screws; three on
back and one on each side
Disassembly & Assembly
3. Pull out the circuit board tray a little and carefully remove two plastic cable protectors
from the cut-out sections on the back of the circuit board tray.
The plastic cable protectors are held in place when the tray is shut, but
they can easily break or chip when removing or replacing the tray. Be
careful not to twist or force the protectors.
When replacing the cables in the cable protectors, keep in mind the
following.
n
The protectors have grooves on three sides and the side
without a groove faces up.
n
The protectors slide halfway under the printer mechanism
frame. If the protectors are not fully inserted under the frame,
there will be a gap between the frame and the top edge of the
circuit board tray.
n
It is a good idea to have an extra protector handy in case you
accidentally break one.
4. Remove the connector cables and FFC cables as described below.
