we have a non color Lexmark MX711de that when it is printing greyscale it is not filled totally in the middle of the page. We are using genuine Lexmark supplies. we installed a new image unit and that did not help. We called Lexmark support and they did not have any solution other than to send out another image unit. We installed the new image unit and the greyscale is only marginally better. Copies from the glass are excellent as are the solid black internal prints, it is very noticeable on the header for fax job log which is lighter grey. The customer prints mainly contract deeds and any signatures or colored writing in the middle of the page are difficult to read, the 2 inches on each edge are very readable. This is the second brand new image unit installed. We have printed the same pages to a different Lexmark copier (same model) and they come out fine, so that rules out computer or IT issues. Sorry, I know it is a long post but I wanted to get all the info in. We are open to any ideas.
