Ricoh AP3800C "Output tray full"


Check the little black piece of plastic that senses the printed page exiting the machine. Our sensor was stuck and I was getting the same message (an similar Ricoh product). When I gently reset the black piece to center, moving freely, printing worked again. I think the sensor got jammed up when we were trying to remove a bad paper misfeed.

Ricoh manuals very confusing on this error message. They refer to standard tray, tray one, etc. without being clear whether it's a paper feed tray or the so-called "standard OUTPUT tray." The output is not really a tray, it's just the depression where your sheet lands after printing. I wrenched on the paper feed trays and their settings for an hour before I figured out they meant OUTPUT.

My printer will only print from bypass tray. Why?


It may be something to do with the paper size settings on printer driver, document print settings or page setup. If for example the computer thinks the paper size is Letter, and the paper in Tray 1/2/3 is A4, it won't print.

Nor printing magenta


If there is toner in the cart but not getting onto the page, the most likely cause is that the toner delivery tube is blocked. You can try removing the unit and vacuuming out the supply line to remove any lumps that may be lodged and then run the forced toner supply in the Service Mode.

Smearned Printing on Ricoh Aficio AP3800C Laser Printer


Hi there the smudges are most likely down to the black PCU (Drum Unit) and following are the reasons for the two fault caode you have given me.

SC 261 LD HP sensor
not switched
off (for K only)
After the laser beam pitch was
changed, it takes more than
five seconds for the HP sensor
to switch off.
• Defective motor
• Defective sensor
• Mechanical problem
when switching the
actuator
• Brown fuse (FU81) on
the Power supply unit
1. Turn the main switch off and on.
2. Check the sensor actuator position of
the LD positioning motor.
3. Replace the LD positioning motor.
4. Replace the LD home position
sensor.
5. Check and/or replace the PSU.

SC 380 Black
development
motor error
SC 381 Color
development
motor error
When the motor speed is
within the target level, the
motor sends a lock signal
(High to Low at CN214-5) to
the BCU.
SC380 is detected under the
following conditions:
• The Lock signal stays High
2 seconds after the motor
turns on.
• The Lock signal stays Low 2
seconds after the motor
turns off.
• The Lock signal stays High
for more than 2 seconds
while the motor is on.
• Defective motor
• Defective BCU
1. Turn the main switch off and on.
2. Replace the motor.
3. Replace the BCU.

Hope this is any help

Thanks J
