I have a Canon imageclass printer that has black copies when a new cartridge was installed. Sent back cartridge got another new one and still have black copies. When I install the original drum unit copies are good. Is it possible to have just got 2 bad units or is there another problem. Thank you. You can see the image on the black pages.

Re: Canon lbp6650 dn. Black copies when new cartridge installed
Hello all,
I have a similar issue, except it is occurring with a Canon PC330 portable copier, a very simple device. It started producing lighter copies so I figured it was time to replace the original toner cart. The first replacement (E40) produced a totally black page. Since I could put the old cart back in and go back to a light copy, I returned the cart to the vendor and asked them to send a different brand this time. Same result. After researching the problem, I focused on checking and cleaning the contacts on the cart, and even pushed the ones in the copier to provide a little more normal force on the cart contacts. This had no effect; the old cart worked but the new one didn't. Both of these were non-Canon products. By now I am thinking that there is some generic incompatibility issue. It seems highly unlikely that two different brands would be defective in the same way by chance, and that buying yet another one is more likely to be an expensive failure. Need to find a way to get some certainty before I spend $120 on another cart.
Does anyone have any successful experience swapping toner cartridges that had produced black output?Comment
