CARTRIDGE (M)
Replace the IMAGING CARTRIDGE (M) with
a new one. (p.271)
Does the error still occur after the replacement?
Check the connection of the DISPENSER

LV TOP
Is the continuity between P/J18 <=> P/J182
normal?
Check the power voltage supply to
4
DISPENSER ASSY (M)
1. Close the interlock switch (HARNESS
ASSY INTERLOCK) before performing
the following work.
2. Measure the voltage between PWBA
MCU ground <=> P/J18-A7PIN, A8PIN.
Is the power voltage (approx. +24 V) output?
