Ricoh MPC305 - Yellow color missing - partial [SOLVED]

[joshuadenmark]

Yellow color missing partial, rest of the colors and black are ok.

Solution:

Remove lsu cover, one screw.

Remove the right lsu, one screw. Be careful not to brake flat cable.
Remove flat cable, one connector.
Put it all together.

Yellow is back.

Hi there!
Yes Peter there is a RTB from Ricoh about this issue. One week ago i was on a Metis/Griffin-workshop, and they having problems with the yellow ph. There are machines, you have to do this proceure every 2 weeks! Until now there is no solution for this. Also hard problems with white lines, coming fro particels in the devbox. Solution ??? I had this several times: Open the devbox, put out the developer, take a sieve, put out the crap refill the developer, done.
Greetings...

Yes, have the developer lines too :-)

When I had the missing color (yellow) I first change the PCDU then Transfer unit and last the Transfer lift motor... 3.5 Hours of pulling apart and putting together OMG

Please tell us if it helped more than 2 week with new coil, we got the same problem with the machine, changed the laster and calibrate the colors, but 2 weeks later they call us again same problem =/

the yellow toner coil had to be replaced due to the copier calling for toner but when the engineer got there fault had cleared this happened 3 times so in the end we changed the coil on the yellow it wasn't twisted like on the spc430 but when turned by hand no toner came out it may have just been blocked this isn't to do with the laser problem

Are you kidding me! Has the SPC430 virus moved to the MPC305 now!? Arggg!!!

Just had this today partial yellow missing first I removed and refitted the RHS laser unit and the fault was still there.

I'm assuming therefor its the one on the left that does the yellow and not the one above the yellow pcu as when I removed and refitted the LHS laser unit it worked only thing I noticed was the flat ribbon clip fell off when I removed it and it was a bitch to refit it.

Spoke to Ricoh UK Helpdesk about the Fault and they Hadn't even heard of it.

happened again todayyellow missing partial having so far swapped the laser unit and the ribbon cables brought it back into the workshop now and whilst in transit for 2 hours when it got back it worked :/

I'm thinking its something on the Bicu as Ricoh released anything on this issue yet does anyone know?
