SOURCE: My printer is telling me to 'replace the bk dev unit (type d) hel

Internal counters control this. Yes! There are 4 of these units: Black, Cyan, Magenta, Yellow, and also 2 drums (Black and colour) You can continue to use the machine. You will likely see a deterioration in quality before long. You will have to contact a Supply company to acquire the units, but you can replace them yourself. Here is a link to the manual if you don't have one:

SOURCE: Replace Color Dev. Unit (Type B) alert

You stated message said replace dev units. Why did you replace the PCU's? There is a difference. The color pcu's can go into any color slot but the deverloper units can only go in one slot. The dev units have a u shaped green plastic part on the front of them and just slide out. The pcus have a little lever and have to be released.

How do i fix the error code f2-00 in AR-M351N copier


HI,

I assume you ran 25-02 when you changed the dev?, if not you will have to replace it again.

Check to make sure you have drive to the dev box, slide out dev box and rub your finger along mag roll and run it up, remove again and see if the dev has returned.

If it is a high mileage machine, you can get problems with the dev drive, the box itself or the toner sensor.

Cheers

the motor is not turning
steps
first take out the dev unit and see if it has toner in it if the dev unit is full then check the sub hopper unit and if any one of these are empty then that motor is bad also verify if you are getting 24v at the motors that are driving the toner into the dev unit 2 motors located behind the primary charge unit cover
if 24v is missing then replace the pico fuse on the dc controller or replace the dc controller
if 24v is present then replace the motor

What is a dev unit?


It is the unit where you slide the toner cartridge into.
There is a material in the unit that has developer in it. That delivers the ink to the drum.
Once you take the toner cartridge out of the machine, you will see one blue shaded phillips screw. Once you loosten the screw the unit will pull out, you can then dump the dev out and install new dev.
You then have to enter diagnostics and clear the developer count.
You press P * C * or # * C *, then enter 25, or 26 and then 06 to clear the drum count and 07 to clear the dev count.

Error code E 020 0181 How do I clear error code? Cannon 1150 color laser copier


Hi

Error code E 020 0181 means that the patch sensor has turned bad or is dirty, to access this try removing eac dev unit and gently unscrew each top so that the patch sensor window is visible. Also, check whether the toner hopper is overfull, it happens sometimes that the toner motor worm gear splits as a result of the hopper becoming packed tight. This may cause the worm gear to split and break if the hopper is 1/2 full or less. You may need to replace toner motor, part number (FH7-1762-030). If the toner motor is fine, then check whether the web solenoid is activating. Clean the web solenoid and ensure free action. This would clear error E020. If the error still not disappears then make sure that the DC controller is fine and the connections from the controller are fine.

Hope this helps...

Estudio350 with error c010, checked the fuser, drum unit , dev unit, all are turning freely, error comes on as soon as fuser comes to full temp


Hi

Error C010 indicates main motor fault. Please check the main motor. If main motor not running under output test, then you'll need to replace it. If motor working, u might need change the LGC board. Take the drum unit out and check inside for any irregularties in drive system belts.

Hope this helps...

Did you change the Magenta stater/ developer? A E020 code is saying that the toner desity is low. Try replasing the developer and run the ATDC for Megenta and see if that helps. You may have a problem with the developing ass'y it self. You may be able to take another colors dev. ass'y with the hopper open and see if the code goes away. The sub code 0124 means that it is the Magenta dev. ass'y
