I am having a 6551 canon copier and I am getting the problem in the duplex. When I am taking copy in overlay mode. the over lay mode first copy is coming and when the paper is in duplex. the second copy is not coming it is moving slightly and jaming the paper

E015 •Clock pulses of the pick-up/duplexing/developing motor fails to be generated or be detected.
•Excess current of the pick-up/duplexing/developing motor is detected.

I do not have a solution for that. A Canon printer tech would know what to do to fix it. But you have to weigh the cost of a fix with the cost of the printer.

it is code for cleaning web. the fuser cleaning web may have tqken up completely if so, replace it. else check sensors which detect taken up cleaning web.

check the paper path you need to control the main drive mecanism, and all bushing roller : registration roller, pickup, fixing and exit: you can see exemple of the bushing to check:

the duplexing unit is under the fixing feeder frame unit..... have only worked on one NP before and it was much like the IR5000 all you need to do is pull out the tray under the fixing frame assemble

pressing (*), then pressing 28 for some seconds, then pressing (*). Choose Copier in the service menu, then options to clear

"No" is the answer to all of those questions, and even if it were "yes", purchasing a good quality refurbished digital machine from a reputable supplier, would still be a far cheaper option than all of that.
Not in or around Toronto, are you?

hi there
there are 2 ways to copy 2 sided
one is full duplex which means your copier must have a duplex attatchment fitted on the copier lid
the other if it hasn't got a duplexer is to copy in 1 to 2 mode which means you have to turn the copy over. it sounds like your machine has not got a duplexer fitted but it can still do double sided using 1 to 2.

hope this helps
