ricoh color

[Shadow1]

Had plenty of problems with the developer not seating, but once you've seen it a few times it's always easy to identify by the color fading more on the trailing edge of the image.
Had quite a few toner pumps fail in the field - hate those little buggers.
In your case, it sounds like this was a machine moved to the shop for recon - if the machine was transported with the toner cartridges in it for any distance, I guarantee toner will clog in the transport tubes. Sometimes you can clear it with a vacuum, other times it's more painful... annother example of why engineers should be arrested and forced to work on their own products.
For the alignment error: Check the entire length of the transfer belt - it's amazing how a tiny mark in exactly the wrong place can affect these machines. Another thing to check is the upper roller the belt rides on - the ID sensors can read a dirty roller through the belt. Last, the ID sensors with isopropanol or denatured alcohol - these sensors sit right below the fuser, and oil and volatiles from the toner evaporate and can condense on them. Barely can see it in visible light, but these sensors are infared, and the deposits can be nearly opaque.

ok sounds very good.did not realize that a mark on the belt would cause an allighnment error.cleaned sensors as advised,checked for dirty roller seems ok,belt has two scores from front to back as though someone pulled the trsn unit out when in raised position.will see if boss will let me use one from our show room for test.could laser unit cause that error.none of the colors line up when i print grid test pattern in color.so thnx very much all excellent advice.will let you know after i swap trans unit.p.s dated a girl from ms tall and crazy always used to say i from then would spell out mississippi? oh well you get the jist.

If it was laser you would probably see other problems or SC codes. If the belt is damaged like that I'll bet you 50 bucks that's the problem.

How tall, and how crazy - I got in-laws like that, but I'm a transplanted yankee (moved down from NJ and wouldn't go back)

[hodgiepodgie]

ok will be waiting for it.put a good unit in same problem colors dont line up line adjust failure,i agree should get laser errors dont know where else to go with it.



6ft and border line nuts controlable.big feet big hands.need big feet to adjust for height.oh and dark chocolate.

That's what I get for betting money I don't have (I have a wife... and 2 kids... and work for Ricoh...)

I assume you have good solids on all 4 colors on a test pattern, the only other solution I can think of before spending $$$ is to do an engine clear, forced process control, forced line position adjustment. After that I'd replace the ID sensors. I had a machine where all this still didn't solve that problem, but it decided to start working again and hasn't quit since - wierd.

The one I was thinking about is 5'11", Big Mouth, Redhead. Not that there's any shortage of insanity to go around...

i know full well i worked for the ricoh gestapo for 22 years.yes i probably should look at i.d will let you know

Very slight scratches or scratches wich aren't placed near the border of the beltaren't that bad but at some point the sensors will indeed have problems to read the patterns. And it's just logical that this will be first noticed with the yellow patterns because they are harder to detect than the other colors. It's also possible that the color registration is not working because the correction levels are messed up too much due to a bad color registration cycle. Sometimes it needs many, manual forced color registrations until the machine is finding the correct values and in some cases you'll have to set the affected SP's to default.If the patterns are running heavily out of a proper registration, you'll definetly have to "help" the machine via the SP programs. But AFAIK these color registration errors does only produce SC285 codes.

Beside of the possibility of a bad transfer unit/belt (a picture of the belt damage would help to say more to this issue) it's still possible that the develompemt process can be (sporadically) disturbed by a bad unit/clutch/unit-drive-connection.

ok jan funny you mention that just got a 285 just before reading your reply.put a good belt on still not passing line adjustment colors allighnment way off.will keeep struggling along thnx for your support one and all.

[hodgiepodgie]

ok 285 was when i put the black unit in i spilt toner so mute point on 285.

I find 1 to 2 sticks of dynamite (or C4 if you can get it) to be very effective at evicting stubborn gremlins such as this one

OK, try resetting 2-916 and 2-909 to it's defaults vaules and force a new line position adjustment

[imthinman]

the 387 is an internal error of the dev unit(out of range).it always is a bad unit or drive to it. if the machine isn't in a constant toner add there is nothing wrong with toner supply system. check your result in line position adjust for the offset problem. do a toner refresh IAW the troubleshooting procedure#2 in the service manual. if someone has cleared RAM you will need to reset your laser adjustments in the guide

[hodgiepodgie]

got rid of the codes.but wont pass line adjustment.forced line adjust still get 070707

yes indead in my marine corps days that would have been my first choice

even after setting the correction values to default?

Just checked, the neccessary procedure is mention in the service manual. It's important that you try this to get the line position adjustment working:

Chapter 4.6.2 - hope it's not different because I only have the german manual.
