The control panel shows the progress of this operation as the percentage completed.
4.The printer prints an AutoJet report.
NOTE:The AutoJet calibration requires that the printheads are in correct alignment. If AutoJet
maps out a large number of jets even though there are no obvious jetting problems, the printhead Y
calibration (a factory calibration) may need to be performed again. In this case, contact HP or your
authorized service provider.

●Printhead X Calibration — the manual version of Auto Head X Calibration.
●Manual Jet Mapping — the manual version of AutoJet.
●Default Registration Data — sets all registration data to zero.
After calibration and jet mapping, perform a linearization or color calibration (as supported by the
RIP). See 
Linearization on page 53.
NOTE:The manual BiDi and X head calibrations are time-consuming and can be error-prone, but is
necessary when calibrating transparent media or other media that the printer’s...

TIP:To achieve the best results from the ruler-measurement calibrations: Use a good-quality
ruler with accurate marks. Use a ruler that is in the same units as the pattern selected. (Do not
attempt to use a metric ruler to read an English-units pattern or vice-versa.) Use a ruler that is at
least as long as the pattern you are measuring. (Do not attempt to add up shorter ruler
measurements to achieve the total length of the pattern.)
To avoid ruler issues, use the image-sensor based calibration.

overprinting previous patterns. For best quality when printing on rigid sheet-fed media, position
the pattern approximately 20 cm (8 in) from the edge.
4.Use the control panel controls to position the pattern, then press Proceed.
The printer prints the registration pattern, then prompts you to advance the media so you can
inspect it.
5.Advance the media by pressing Move Belt Forward, then press Proceed.
The control panel displays this prompt:

The control panel asks whether you want to print a manual head-to-head calibration page.
●If you need to print a new calibration pattern, press Proceed. The printer prints a calibration
page.
When the calibration page has printed, the control panel displays this prompt:
Take readings from left side of pattern.
●If you have a calibration pattern from a recent print, you can use it to calibrate the heads.
Press Cancel and go to the next step. (For best results, do not use a previously-printed
pattern,...

Print Jet Map?
If you have a calibration pattern from a recent print, you can use it to calibrate the heads. Press
Cancel and go to the next step. Otherwise, press Proceed..
The printer prints a jet map test pattern.
If a line segment is missing or broken, the jet number shown next to it is out. A code letter if
present provides further information:
●R — no replacement
●S — user disqualified “soft” jetout
●H — user disqualified “hard” jetout
●D — disqualified (and replaced) by AutoJet

Clear Individual Bad Jets
When you select Clear Individual Bad Jets, the control panel displays the following prompt:
Head 1: Press Proceed (►) to clear a bad jet.
1.Press ▲ and ▼ to select a head number, then press Proceed (►).
The control panel displays a numeric keyboard that you can use to enter the number of the bad
jet.
2.Enter the jet number, then press Enter.
3.When you are finished entering jet numbers, press Cancel.
The control panel displays the head selection message again.
4.Press ▲ and ▼ to...

The head selection screen appears.
5.Repeat steps 1 through 4 for any other printhead, or press n to return to the menu.
Clear All Bad Jets
When you select Clear All Bad Jets, the control panel displays the following prompt:
Are you sure you want to clear ALL reported bad jets?
●Press Cancel to cancel this function, or
●Press Proceed. The control panel displays this message:
Do you want to clear the hard bad jets?
●Press No to clear the soft bad jets only, or
●Press Yes to clear both the hard and soft...
