Repeating print pattern, quality problem

[peterbax]

Thanks Gabi

What is strange is I have put probably 7 cyan toners through the machine over its life and never had this issue before, then I get 2 faulties in a row of the same colour, just weird. The toner that was removed with the first fault had been in the machine for 6 months plus so I dont beleive more prints would make any difference.

I didnt realise they had a expiry or use by date

I have another new one to try turned up today, bit scared to put it in

Hi,

That is because you store the cartridges for a long time and the drum stay in contact with the charge roll. Try to make more prints with the "new cartridge ", maybe the problem will go away.

C3290 we have had for several years, great unit. Last year I replaced the toner cartridges as I have done many times before, bought 2 toners off an online reseller, genuine catridges

The new Cyan toner installed displayed a repeating pattern 28mm in spacing long and about 25mm spacing across, so every 28mm along the length of the page there is a set of 8 equally spaced small wavy Cyan lines each about 10mm wide x 2mm high. On doing a bit of research it appears that this is a roller aprox 8.9mm in diameter and I had to guess inside the cartridge itself a defect exists.

I persevered with this for quite a while until it got the better of me and I relented and put the second new toner cartridge in figuring that I would just throw the faulty Cyan one away.

but on install the second new cartridge displayed almost identical behaviour, same spacing and defect and only the Cyan.

I find it hard to beleive that i have got 2 faulty catridges with an almost identical problem but that is what it seems like as there is nothing else that creates that repeating pattern spacing

Have half printed a page to eliminate the fuser and it seems that it cant be that

Anyone have any other ideas, I have ordered another cartridge to try and hopefully fix the problem but if that fails I really will need an explanation other than the cartridges.
