Re: msg

I'm not that familiar with your model, however, the ##324 error is a scanner failure. On some of the Canon models, there is a provision in the menu for re-calibrating the scanner. You try this but I can't guarantee it will fix your problem. If I'm thinking right, your model corresponds to the Hp LaserJet 3100 series (but then again, why should I start thinking right now?). They where notorious for that problem. You'll need a blank sheet of white paper, look through the menu to find "calibrate scanner". I'm still trying to find more information on this, but I don't have it yet Hope it helps Ed

Check printer msg and audible alarm sounds. If I unplug the fax and wait 30 seconds and plug it back in alarm stops and check printer display is gone

If its a ## error its a internal fault like the fuser or laser!If it the fuser just before it starts to print it will say check printer and stop!Take it to the nearest dealer and let them have a look at it!

CHECK PRINTER ##330 flashing message

From the message board archives:

Error codes:

## 322 Fuser not heating (Usually Bad Fuser Module)
## 323 Laser Beam detect error
## 324 Laser scanner motor rotation incorrect
## 325 Fan motor inop
## 330 Power Supply (Replace/Repair)

You must turn on error management to have the machine display error codes, otherwise it will just say "CHECK PRINTER".

To turn error management on, enter the following: Press Data registration, #, Set, 00000011, set, stop. Now after the "check printer" message there should be one of the error codes above.

Supposedly, Nation-Wide Repair Service fixes the bad power supplies for $45.00. They can be reached at 800-798-1814. You can also buy one for $148.00 from I hear. The proper replacement power supply part number for both the LC7000 and LC7500 is HH3-5278 so I am told.

This error is a laser motor error. You can try to lube the laser bearings by taking apart the laser assembly, most likely you will need to get a replacement

The alarm light is blinking. We have unplugged it and it's still on.

alarm flasing can be more than one thing. check to see if alarm is representing a symbol on fax machine. It can be jammed paper inside, or toner/ ink run out.

I have a Canon printer, Mod.# MP450. I am getting an "error code 5100" on the screen. Additionally, the off/on button is blinking green and the alarm is blinking yellow. I have been also...

firstly, hi, any way check that ur ink cartriges are not low. if not you may have a software problem. Try uninstalling the software, taking the plug out of the back and try again. Install the software and turn the fax back on. It may work, if not u may have an hardwear issue, return it tp Canon with the warranty on the fax

Keep saying check printer ##324 [Rx] Printer section scanner motor rotation rate abnormal 0003-5251
An internal mechanism is faulty.
1) Check the connection between the laser scanner unit (J802) and SCNT board (J6).
2) Replace the laser scanner unit.
3) Replace the SCNT board.

Check printer

The machine probably needs a new fuser assembly. Not easy or cheap!
