No transfer of Image! - Toshiba 1360 Black and White Copier

C360 error: "Replace Image Transfer Belt Unit"

The error message under that title is "Have the image transfer belt replaced soon." It's a new unit, but resists doing the Gradation Adjust. Tried returning the old belt (which was working before the replacement) and error message remains, so apparently the problem is not with the new belt.

System Error Clear (System 1 -> Initialization) gives "Result: OK" but has no effect; the problem remains after machine restart. However, it does NOT at any time give L-5 error (Transfer belt unit accumulated rotation time excess warning), just continues to say "replace image transfer belt unit", and will not allow anything else to proceed. What am I missing? (Transfer belt clutch malfunction?

One of two possibilities. 1) Printer memory problem. 2) high voltage isn't correct.

See page 103 of http://downloadcenter.samsung.com/content/UM/201112/20111205134621713/EN/English.pdf. It looks like the clx6220 uses a transfer belt to transfer all the different toner powders to the paper.

The transfer belt unit is refered to also as the image unit !
Also each toner cartridge contains the OPC drum and is replaced when you replace a toner cartridge by the look of it.
You need a transfer belt to transfer the image to the paper and this is why they call it an image unit.
I am guessing that the transfer belt needs replacement !

Check the transfer belt unit contact and that of high voltage board for connection and clean or correct the contact.
Change the image transfer belt unit.
Clean the sensor windows on the transfer belt unit.

• The 1st Image Transfer Retraction Position Sensor
is not activated (retracted position) within 5
sec. after the 1st Image Transfer Pressure/
Retraction Motor has started turning during a
sequence of the Transfer Belt's retracting motion.
• The 1st Image Transfer Retraction Position Sensor
is not deactivated (pressed position) within 1
sec. after the 1st Image Transfer Pressure/
Retraction Motor has started turning during a
sequence of the Transfer Belt's pressing motion.

you need the retract motor or the sencor that sees it

Normally a blank copy is caused by the image not being transfered from the drum to the copy paper. Which indicates a problem with the transfer step of the process, check for a bad transfer roller or a bad transfer belt. If this is not very obvious, run a copy and try to turn the machine off or open the front cover during the copy process when the copy paper is about half way under the drum and check for a toner image on the drum. If there is no toner image on the drum you may have a developer problem, broken drive gears etc. But if there is a toner image on the drum but no image on the paper then it is a transfer issue.

Hello I think I can help you. I Would not use T shirt transfer when you make up your print I would select poster print or any other form that does not automatically reverse the image. The reason your software is designed to do this is on the regular transfer paper your laying the image down on the shirt, so for it to come out right it has to be reversed. With the dark T shirt transfer paper your peeling off the backing and putting the image face up on the T Shirt.

open cover, remove image transfer unit, behind ITU is 2nd image transfer roller, move it with hand, check solenoid and sensors, thaht they moving freely.
restart

good luck
