Some patterns appearing on the copies
I replaced the drum and the blade (new) but still the problem presists. When blank copy is taken a type of pattern appears on the blank sheets and when fully open (platen cover) copy is taken some dots appear,I have attached copies of it.
I want to know what could be the cause for it ??? and how to solve that problem.
Can any body help me in this regard.
thanks

Copier model?!
Practice makes perfect
If it ain't broke, don't fix it
A picture is worth a thousand words
If you want something done right, you have to do it yourself
Do these patterns appear on prints? Have you checked the developer mag roller?
Totoro
Model number please?
Just in general terms it looks like a charge related issue. Anything more specific will depend on the model. =^..^=
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

replace the Developer Unit
**Knowledge is time consuming, exhausting and costly for a trained Tech.**
I have seen this on a ir5000, where the coil of the drum cleaning unit was broken so the waste toner could not hauled away. This lead to stuck waste toner in the cleaning unit and generates exactly this printout.replace the Developer Unit
check this first.
If this is an older, maybe analog model, i am with teckat, replace the spacer rollers which generates the distance between developing cylinder and drum

Re: Some patterns appearing on the copies
Dear Friends
Thank you for your replies
My Machine model is IR2018 Canon.
Developer unit I cleaned well and checked for any leaks, and the rollers I checked, It seems every thing is fine.
I am attaching a scanned copy of the sheet which is copied on this copier. You can see the patterns on the
sheet.
I have a doubt, Is it related to any memory (RAM) problem ????
Please friends do reply
How many copies have machine? Swap developer.

... along the same lines: I've seen the same effect when the main charge is cranked all the way up, and the carrier is being pulled from the developing unit. Start with new developer, then look at charge settings. =^..^=

no Developer at all, Canon B/W Mashines use one component Toner. Replace the whole Drum unit, looks for me like a Charge Roller problem.
