Reasons for Epson printer will not print from computer

Jammed paper. Ink cartridge issue. No paper is installed. Outdated printer driver.

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.

Check your network connection as well as your network devices like your router and modem. View the network connection status of your printer and see if your printer is properly connected to the network. Reconnect or replace your network cable when necessary if your printer is using wired connection.
Check that the correct paper is properly loaded into the printer and is not jammed. Replacing damaged cables, plugging in loose or disconnected cables, and fixing paper jams as necessary may resolve the issue.
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.
Clean the print head, if necessary. Make sure the paper size, orientation, and layout settings in your printer software are correct. Make sure your document does not contain blank pages. If your printer software has a Preview option, you can check for blank pages before you print and remove them, if necessary.
Do a hard reset on your printer. To do this you just need to turn off your printer, unplug for a few minutes and then plug the printer again. If that still doesn`t work, try turning the printer and your computer off, and then start it back up again. Try uninstalling and then reinstalling your printer driver.
First, clean the nozzle using a damp cloth or an alcohol wipe while the nozzle is hot. This may cause some steam but will indeed remove any material clinging to the nozzle. If this doesn`t work, you can also use a wire brush, small blade, or needle to remove any remaining debris from the nozzle.
Even if your cartridge is full and ready for action, it may have become slightly dislodged and no longer in full electrical contact with the printer. The easiest way to rectify this potential problem is to simply remove and reinstall the cartridges.
If you have problems feeding paper, try these solutions: If paper does not feed for printing, remove it from the rear feed slot or cassette. Reload it, then adjust the edge guides. Make sure the paper stack is not above the tab on the edge guides inside the cassette or rear feed slot.
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.

Paper feeds straight through without printing on an Epson R2400
ANSWER : I was able to get it to print the internal test page by holding down the sheet paper feed button while turning the machine on — then continuing to hold the sheet paper feed button. It took several attempts, feeding a page straight through, but eventually it caught the sheet and printed. So it may be a timing issue as others have mentioned. It could still mean that the feed rollers are worn out. The back side of the large D-shaped feed roller has visible abrasion on it. The abrasion is difficult to see as the roller does not stay with the flat side exposed.
