HP Envy 7640 Ink Cartridges Issues

 If your hp printer shows an error light in the printer’s control panel, please don’t panic. Here are some solutions:

   Firstly, check for the ink levels. If any of the ink cartridges or all the ink levels are low, then change the specific ink cartridge.

   For best quality prints, always use hp ink cartridges, which are made to work with the specific hp printer model. Each different model has different ink cartridges provided by the hp printers. You can get them from HP Sure Supply easily.

   Check whether you have installed the ink cartridges in the holders properly. Keep your printer turned on. Without turning off your printer, open the cartridge access door. Wait until the cartridges become idle and then place your finger over the cartridges. Slowly, move your finger over the cartridges and see whether all the cartridges are placed equally. If any of the ink cartridge is little bit raised from its position, please correct it. Reinsert the cartridges for several times. Try to print now.

   Open the cartridge access door and take away the cartridges from the holders. Make sure that no packing materials are left in the cartridges. Then, take a clean, wet cloth and clean the electrical contacts in the cartridges. Allow it to dry for some time. Reinstall them in the holders again. Try printing now.
