ENWW About the ink cartridges 75 Replace an ink cartridge There are two occasions when you need to replace an ink cartridge. — ● The ink cartridge is very low and you want to replace it with a full cartridge for unattended printing (you can use up the remaining ink in the first cartridge at a more convenient time). The ink cartridge is empty or faulty, and you must replace it to continue printing. CAUTION: Do not try to remove an ink cartridge while printing. CAUTION: Remove an ink cartridge only if you are ready to insert another one. NOTE: When a cartridge runs out of ink, the current job is cancelled. If your printer is on a stand, make sure the printer wheels are locked (the brake lever is pressed down) to prevent the printer from moving. Open the ink cartridge cover on the left-hand side of the printer. Make sure that you insert the ink cartridge into the slot that has the same colored letter as the cartridge you are installing. About the printhead The printhead, which is supplied installed in the printer, is connected to the ink cartridges and jets ink onto the paper. CAUTION: Observe precautions when handling the printhead, because it is an ESD-sensitive device (see the Glossary on page 143). avoid touching pins , leads , and circuitry.
