Q:When a new cartridge is inserted, the printer sometimes states the new cartridges to be half full. Why does it happen?
· The printer only estimates the level of the ink in the cartridge. It is not a precise measurement.
· The new cartridges should be full and should last as long as normal.
Q:When I print a sheet, the colours do not exactly match the ones displayed on my screen.
· Differing monitor drivers will produce slightly different colours and therefore the colours displayed on your screen will always be slightly different than the ones that your printer prints.
· You could try to match them but each program uses a slightly different driver and therefore each colour scheme is slightly different.
Q:Vertical lines are not aligned or vertical banding appears. How do I align the print head on my printer?
· First make sure you are using the most current version of the printer driver.
· Most printers will have a utility function which will give you an option to allign the printer head. Follow the instructions on the screen.
· Make sure to use the printers power switch to turn off the printer,otherwise the settings will not be saved.
· If you have already tried to align the print head and did not have any success,try turning high speed off in the printer driver settings.
Q: Sometimes when a OEM cartridge is installed, a warning prompt states that "Non-genuine cartridge is installed, continue?" why does this happen?
· Warning prompt is set by the printer manufacturer.
· Click YES to continue printing.
· There is no impact on printer and printing quality.
Q:After the cartridge is inserted into the printer, why does the printer not recognise the cartridge?
· Take the cartridge out and reinstall it again.
· Use a dry cloth or paper tissue to clean the chip and reinstall it.
