This document is for the HP Photosmart Premium e-All-in-One Printer Series (C310).
note:Inappropriate, damaged, or unsupported paper can cause vertical streaks in printouts.
Examples of horizontal and vertical streaks in a printout
|
|
If your printout contains horizontal lines or other print quality issues besides vertical streaks, continue to the next step.
|
Do not replace cartridges for vertical streaks in a printout. Instead, check the paper as described earlier in this document or search for a document that covers this issue. Vertical streaks in copies can often be fixed by cleaning the scanner glass.
|
note:Ink level warnings and indicators provide estimates for planning purposes only. When an indicator shows low ink levels, consider having a replacement ink cartridge available to avoid possible printing delays. You do not need to replace ink cartridges until print quality becomes unacceptable.

note:Make sure that each cartridge is installed in the correct slot. Match the shape of the icon and the color of the cartridge with the slot that has the same shaped icon and color.
note:Mechanical noises during the cleaning process are normal. A test page prints when the cleaning process finishes.
caution:Never turn off the printer when ink cartridges are not installed. To avoid issues that require cleaning the printhead or that can damage the ink system, always replace ink cartridges as soon as possible, and always turn off the printer using the Power button.
caution:Do not lift the latch next to the carriage to install the ink cartridges. Doing so can result in incorrectly seated ink cartridges and printing problems. The latch must remain down to install the ink cartridges correctly.
note:Never turn off the printer when ink cartridges are missing. Make sure that you replace any missing ink cartridges as soon as possible to avoid print quality issues and possible extra ink usage or damage to the ink system.
caution:Make sure you remove the orange pull-tab and plastic wrap completely before you remove the orange cap in the next step. Otherwise, ink might leak from the ink cartridge. When you remove the plastic wrap, the paper label on the top of the ink cartridge tears slightly, which is necessary to properly vent the ink cartridge.
caution:Do not lift the carriage latch handle to install the ink cartridges. Doing so can result in incorrectly seated ink cartridges and printing problems. The latch must remain down to install the ink cartridges correctly.
caution:Be careful not to bend the tab out more than 1.27 cm (0.5 in). Moving the tab too far might damage the ink cartridge or cause the tab to break off.
caution:Wait until you have a new printhead assembly available before you remove the cartridges. HP recommends that you do not leave the cartridges outside the printer longer than 30 minutes. This could damage both the printer and the cartridges.
note:Keep a print sample that shows the problem. If the ink cartridges, printhead, or printer is replaced under warranty, the support agent will request the print sample. If the printer is returned to HP, the print sample must be returned with the printer. Place the sample in the output tray when you package your printer for shipping.
