MPC 1500 sc 202

[ash_572]

customer complained that the magenta was not printing. did the head cleaning 3 times. still the same. printed the nozzle test patern and the magenta was completley blank. tried to flush the magenta head and i ended up with the sc code of 202.

checked the ink full sensor and it seemed alright. am not an inkjet expert i just happen to have more experience on these types than any other engineer where i work.

Had this exact problem last week. I changed the maintenance unit and waste ink tank, reset the pm counters and reset the waste tank b counter in sp 2xx.
There is also a tech bulletin re the print head carriage where you have to take it out and push the slider down with a small flat blade.It's in the service manual on the disk

also i couldnt get into service mode. the 0 button wouldnt work is there another code that i can try?

[aabarnes1]

Ah! Sorry, I don't know. But if there is a way you're sure to find out on this site or from the 'experts' at Ricoh.

replaced maintenance unit and still no difference

Try a super flush in SP modes. If that doesn't work it's a new engine unit.

its now bought up an sc 310.

[TonerMunkeh]

310 isn't listed in the manual. Do you mean 210?

[ash_572]

sorry. its sc 210

That's the main scan encoder signal error. This little machine sounds rather miffed at itself at the moment. Replace the engine unit and look at the main scan encoder too.

im trying to fix it without having to replace the engine unit. engine for this type cost about a grand.

You mentioned in an earlier post that you could not enter sp mode? if that's the case then there is no point in replacing any parts in this machine as you need to go into sp mode to tell it that you have replaced the maintenance unit/engine/waste tank etc. The encoder wheel can be cleaned carefully with alcohol. I would't just jump in and throw a new engine at it as previously suggested. We're notall in a position to throw parts at a machine and hope it fixes it, know what I mean!!!!! Let us know how you get on with this cos we've had a few problems with these bags of shite aswell, good luck.

Don't clean the encoders with alcohol! Use water!

Alcohol takes the coating off the strip and wheel and makes them unreadable by the sensor.

ive replaced the whole keypad. service mode is working.

already cleaned the encoders with alcohol and still the same. encoder looks clean anyway.
not many engineers know much about these machines coz these are a pain in the ass to work on.
