HP Designjet T7100 Printer series - Manual (Page 68)

NOTE: If the paper has jammed, it is recommended that you reinsert the printheads and initiate the
realignment procedure with the Image Quality Maintenance menu .
CAUTION: Do not use transparent or semi-transparent paper to align the printheads.
Reinsert printheads procedure
1. If the realignment process is running and the wrong paper is loaded, press the Cancel key on the
front panel.
CAUTION: Do not print if the realignment process has been canceled. You can restart the
alignment with the Image Quality Maintenance menu procedure.
2. Load the paper you wish to use, see Handle the paper on page 26 . It should be at least 420 mm
(16.54 in) wide.
CAUTION: Do not use transparent or semi-transparent paper to align the printheads.
3. Remove and re-insert all the printheads, see Remove a printhead on page 51 and Insert a
printhead on page 54 . This starts the printhead alignment procedure.
4. Ensure the window is closed, as a strong light source near the printer during printhead
realignment can affect alignment.
5. The process takes about six minutes. Wait until the front-panel display shows the process complete
before using the printer.
NOTE: The printer prints a calibration image. Do not worry about the image. The front-panel
display shows any errors in the process.
Image Quality Maintenance menu procedure
1. Load the paper you wish to use, see Handle the paper on page 26 . It should be at least 420 mm
(16.54 in) wide.
CAUTION: Do not use transparent or semi-transparent paper to align the printheads.
2.
From the front panel, select the Image Quality Maintenance menu icon , then Align
printheads. The printer checks to see if it has enough paper to run the realignment.
3. If the loaded paper is satisfactory, the printer runs the realignment and prints a realignment
pattern. Ensure the window is closed, as a strong light source near the printer during printhead
realignment can affect alignment.
4. The process takes about five minutes. Wait until the front-panel display shows the process
complete before using the printer.
Scanning errors during alignment
If the alignment process fails, a Scanning problems message appears on the front panel. This means
that the alignment has not completed successfully. Therefore the printer is not aligned and the alignment
should be repeated before printing with good image quality. Possible reasons for failure:
● The paper used was not acceptable; repeat the alignment with a different paper type.
● The printheads are not clean; see Clean (recover) the printheads on page 56 .
● The window was open; repeat the alignment with the window closed.
