Mostly from the Red color that is having problems. Ink shows that we are 75% or more fro all the colors and Black is printing fine. What can we do to correct the problem

I am sorry to hear that the cartridges are preforming poorly! We do have a 1 year warranty and would be glad to help! The OPC drum is covered by a spring loaded plastic shutter. Lift the spring loaded shutter to view the OPC drum. Do NOT touch the OPC drum. Visually inspect the drum for damage or debris. If need be, a clean, soft, dry, lint-free cloth can be used to gently wipe the drum. Do NOT use moisture of any kind. After doing this please try rocking the toner side to side. If all fails please call in at 888-321-2552 and speak with our customer service representatives.

Sometimes spills toner Both of the two toner cartridges I have used spilled toner, resulting in magenta smear streaks to pages. June 3, 2014
This is a great company I've purchased this item twice now (along with the other 3 colors) and have purchase lots of compatible ink in the past. I had an issue with one of these toner carts...it was forming a line on every sheet. LD was great, no questions asked, they replaced it and replaced it quickly. They heard it wasn't right and fixed it. The price was great too...not the very cheapest, but almost. I pay the little bit more, just because they fix what's not right. The quality is always good. Literally only had one issue and as i said it was fixed before I knew what happened. Great products, great company! April 5, 2012
