HP Designjet Z6200 Photo Printer - Manual (Page 67)

● Print quality may be impaired.
● The printer will be unable to estimate the ink level in the cartridge, and will report it as empty.
To force the printer to accept cartridges that it believes to be empty, follow these instructions:
1. Install the cartridge in the printer (see Insert an ink cartridge on page 62 ).
2. The front panel will complain that the cartridge is empty, and the cartridge removal process will
start. Press the Cancel key to stop this automatic process.
3.
At the front panel, select the icon.
4. Highlight Replace ink cartridges, but do not select it.
5. Press the Cancel key and the Up key at the same time, and hold them down for at least two
seconds.
6. The front panel will display a series of warning messages. In response to each message, press the
Cancel key to cancel the process, or the OK key to confirm that you wish to continue.
When you have pressed OK in response to all warning messages, the front panel will give the usual ink
cartridge status display, but the cartridge will be shown as empty with a warning sign.
Printheads
The printheads are connected to the ink cartridges. They use jet action to put ink on the paper. Each
printhead has two ink-cartridge connection points and two sets of nozzles, which means that each
printhead prints in two different colors. For example, the printhead below prints in magenta and
yellow.
The printheads are extremely durable and do not need to be replaced every time an ink cartridge is
replaced. They provide excellent results even when the ink cartridges contain a low level of ink.
To maintain optimum print quality, the printheads are automatically tested at regular intervals, and
automatically serviced when necessary. This takes a little time and can occasionally delay printing.
When a printhead eventually needs to be replaced, the front panel will display a message.
To check the status of the printheads, select the icon, then View printhead status.
CAUTION: Avoid touching pins, leads, and circuitry when handling ink cartridges because these
elements are sensitive to electrostatic discharge. Such devices are called ESD-sensitive devices. See
Glossary on page 207 . Electrostatic discharges are one of the main hazards to electronics products.
This type of damage can reduce the life expectancy of the device.
