Stray Toner marks on IR1024

[cokwax]

I have a weird problem that most technicians have failed to solve. The drum attracts stray toner on the left hand side and transfers to paper. See attached image . Tried changing drum unit - same problem. Any help is greatly appreciated

Random Alligator / Water Marks on the Copies

Caused by a bias leak in the developer assembly.

Follow the guide lines below, to resolve this issue. 1) Make sure that the developer area is clean.
2) Rebuild developer assembly.
3)In some cases you will have to replace the developer assembly

As well, check to make sure that the leaf spring grounding plate of the Developing Assembly is not loose and that it makes a proper contact.

Looks like a broken dev spacer to me. Check the spacers at the ends of the dev roll. They set the gap between the drum and the dev cylinder. Or you have a staple or something in dev housing.Looks similar to problems on np1020...remember those?..LOL.Swap the dev and see if it goes away

Replace the dev spacers.

Replace the dev spacers.

Canuck and DAG were right.
I replaced the spacers and the problem was solved.
Thanks a lot comrades.

I however still have a problem with mag roller cleaning blade. It got worn out and the print quality is greatly affected. It is a pain getting a new developing unit for IR1024/IR1018 here in Uganda.

Re: Stray Toner marks on IR1024

well i usually take the developing unit give it a good clean up, use a good cutting blade to gently scratch out the soiled in the cleaning blade, also get a plastic not very hard dish washing sponge and with the harshest part give the developing cylinder a good scrub, that usually words a first time but doesn't help if done a second time but at least i save one substitution, then again that's just my method

in olden days - i used BRASSO to clean dev. cylinders on NP copiers / worked like a charm

Re: Stray Toner marks on IR1024

haven't tried that but will soon, and i'd bet it would still work nowadays, always scrubbed it dry, everyday you learn something new lol

Re: Stray Toner marks on IR1024

Uau that's how i do on these new ones also except i don't use brasso or any liquid just the non scratch green pad and then a clean cloth, still manage to reuse them for another turn at least and being aluminum the brasso or alikes makes all the sense but never thought of it good job

Yes, Brasso is a good stuff to clean those magnetic rollers, doctor blades etc. Although I rarely use it these days, it used to be an integral part of my tools not only for the NP copier series, but also in my days as a tech then working with Gestetner-Mita. Most of the drums for the mita were made of Selenium materials, polishing them with Brasso would really rejuvenate the drums. It was a wonderful experience.

Getting a new developing unit for the ir 1020 series copier here is indeed like 'squeezing water from the rock'! I bet even the official canon rep here doesn't have, or if they they can get you one, then it could cost you an 'arm and leg'. The best you can do is to look for a good working one from among the copier junks. Ask your techs to help you look for one. Or try the 'SCREW TAPE' offer from New York?.

Yeah the old NP dev cylinders that were silver..cleaned them with Soft Scrub. When NP6230 came along,they started coating cylinder with black layer. It scrubs right off. Those babies..bare it,wipe it with alcohol. No go,change the cylinder. And that blade in the dev housing..it trims the thickness of the toner layer on the cylinder..us old school duplicator days techs call them trimmer bars.
