Energy shutdown
To resolve an energy shutdown, do the following:
1. Clean Slider Rods and Apply Oil along the complete axis of the Slide Rods. After applying the
Oil, perform the Scan-Axis Test
See Scan Axis test on page 87 and check that the values are
within the given limits.
2. Clean the Encoder Strip
See Clean the Encoder Strip on page 422.
3. Perform the Scan-Axis Test to obtain further information on the problem
Scan Axis test
on page 87.
Vacuum suction much lower at high altitudes
At altitudes above 3,000 meters, the vacuum force holding down the paper will be lower, therefore the
paper will not be held in place properly causing:
●
Ink Smearing on the Paper.
●
Printhead crashes against the Paper.
●
Roll Paper loading problems (low probability).
Banding at variable extreme environmental
conditions
NOTE: This problem is only applicable if the OMAS is disabled.
Since the Accuracy Calibration has been done at normal environmental conditions, printing in extreme
environmental conditions will cause banding because the advance of the Drive Roller does not
correspond to the same conditions that the calibration was done in. To solve the problem, try the
following:
Perform the Accuracy Calibration in the new environmental conditions (see Using your printer).
Printhead crashes/smears on high-density prints
using coated paper
High-density prints can cause cockle mainly on HP Coated Paper. This causes two main problems:
1. Cockling in the borders - Because the printer places too much ink on the Coated Paper, the
borders of the print become raised, causing the Printhead to crash against the paper. To solve the
problem, add a 15 mm white margin to the edges of the images.
2. Cockling within the print - If the printer places too much ink within the print, the paper starts to
ripple, causing the Printhead to smear against the paper. To solve the problem, try the following:
●
Check in the Front Panel if Ink Limiting is ON or OFF. If Ink Limiting is OFF, turn it ON.
●
Avoid using HP Coated Paper for high-density prints. As a substitute, use HP Heavyweight
Coated Paper.
