ERROR SC682-223 ? Also, Error for CPU cyan at starting.

Turn the machine off. Open the access door and remove the cyan photoconductor unit. Check the contact pins are straight and undamaged. Gently reinsert the unit. Turn the power back on. If the machine still does not recognise the pcu is inserted it is probably damaged and needs replacing. How many copies/prints has your machine done?

AC charge output error [Cyan].
Poor connection with the PCU.
Check for broken connector in machine where the PCU goes into.
Defective PCU.

I used can air and blew out the reverse button area. Worked immediately after turning off and back on.

SC302 on a D029 (MPC2800) machine is due to Cyan A/C charge output error or a bias leak on HVPS. Could be a defective PCU or defective HVPS. Check charge connections to PCU, replace PCU and if this doesn't resolve issue, replace HVPS.

Hi,

Please follow the solution in the link below. Also as you putting in the cartridge always check for loose toner in the area and on the cartridge itself as this can block the sensors.

cyan problem --check if cyan pcu is set properly or replace cuan pcu(drum)

You need to remove the cyan cartridge, and thoroughly clean the inside of the printer (please use proper printer cleaning kit, not a damp cloth!). The sensors can get crudded up with loose toner inside the machine.

ensure that the one you install is the exact model name and number, if this is correct, try unistallling once again and check one more time,

you might want to get a new cyan toner if this still fails, i dont think there is a prob in your machine, cheers

Take all carts out of the machine. Have a look into the cart holder. Is there ink swapping beneath the white plastic? (You might shake the machine ;-)

If yes, the cart holder leaks and needs replacement.

If not (your lucky!) it could be that the automatic cleaning procedure which starts when a cart is changed has soaked the carts empty.

Do set machine with date and time and NEVER unplug NOR use a power switch which breaks the power supply.

Do use constant power and switch off machine by pressing stand-by-fax-button!

Everytime when machine comes to (new) power contact it runs an extensive ink cleaning procedure. thats why your carts are always near empty....
The stand-by will prevent this and machine does some cleaning procedures which consumes only a few drops(!) of ink!


The display asks you if you have changed the carts. Do answer this question by pressing 1 for YES or 2 for NO.
This will reset the built-in inkcountermanagement to the correct settings

problem might be with toner recycle coil which runs around the back of the belt unit. as the cyan unit is the furthest down the line if any blockages occur it can back up and lift the drum unit up. check the square opening of the recycle unit on the cyan end. Make sure you change waste toner unit when prompted or you might break a gear (big job) Karl Oki engineer
