The Cause of Clogs

Printheads clog because nozzles get blocked by either air or ink. Clogs usually happen when: You keep printing with depleted ink cartridges. Using empty ink cartridges can result in air bubbles that can clog your cartridge and/or printhead.

1 Open the paper support and pull up its extensions. 2 Open the output tray and pull out its extension. 3 Press in the release button and slide the edge guide to the left. 4 Load paper against the right edge guide and behind the tab.
If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.
If paper dust builds up on the rollers, they may lose traction and become unable to feed paper properly. Clean the paper guide. If roll paper does not feed, cut the end straight across and uncurl it by rolling it backward, if necessary. Then reload the paper.
There are a number of reasons why this might happen. In a large number of cases we come across, the photo paper weight (which is measured in GSM) or overall thickness exceeds the printer`s ability meaning it is too think or too heavy for the rollers to successfully handle.
The common reasons for this issue are various, for instance, the paper input tray is overloaded, dust or moisture can affect the paper feed or paper pick rollers, the printer driver is old, etc. Thus, the printer cannot detect the paper that has been inserted into the tray.
There are a few things that could be the cause of this problem, including: Empty ink or toner cartridges that need replacing. Ink or toner cartridges that have become dislodged from their proper place. The wrong paper size loaded in the input tray.
As a rule of thumb, to achieve photo quality print, you will need to use an image resolution of 300 pixels per inch. We write this as 300 DPI and means that in each inch of your print there will be 300 pixels.
Several factors may cause the product to print blank pages, such as print settings, low ink, or the product itself. Check the following: Make sure the product is placed on a flat, stable surface that extends beyond the base in all directions. The product won`t operate properly if it`s tilted or at an angle.
Ensure that the supported settings are applied in the printer driver and click Print in Black to continue printing using Black Print Mode or Cancel Print to replace the expended cartridge.
Press the home button, if necessary. Press the left or right arrow button to select Maintenance > Reset Ink Level. Press the start button, the OK button twice, and then the start button again. Press the right or left arrow button to highlight the ink tank you refilled and press the OK button to select it.
Ensure that the supported settings are applied in the printer driver and click Print in Black to continue printing using Black Print Mode or Cancel Print to replace the expended cartridge.

Prints blank pages, won't print from computer
ANSWER : Don’t know why you replaced the fuser, but assuming you had print before, then it must have been something you did during the procedure. Only thing I can suggest is to recheck your work. Just because you reinstalled a connector doesn’t mean that it is seated firmly enough to work. Any flat ribbon connectors that you removed and reinstalled, check to see that the contacts are all flat and not peeled back.

Print file sent but no printing occurs
ANSWER : Been working on these since they first were released. Never seen a problem like yours. If it happens again, try doing an engine test, as it bypasses the formatter board. The engine test is located at the right side of the manual tray opening. Look for a hole in the side wall. Stick something like a paper clip into it to actuate the test button. It will then print a lined test page. If it does that, then it points to the formatter board as the cause of your problem.
