Overview
A properly adjusted mechanism provides optimum print quality without impacting the media handling capability of the printer. Print quality improves as the nozzles come closer to the paper. If the print cartridge is positioned too close to the media, however, the printer may experience paper jams, print skew, or print smear.

The proper PPS distance is between 28 and 58 mils. The setting is impacted by the rotation limit of the pivot assembly and the height of the carriage rod. When adjustment is necessary, always try to pull t |

Adjusting the Carriage Rod
1. Replace the right and left bracket screws (part number 0515-2522). Do not tighten the new screws. The washer, however, should just touch the bracket.
Note: The screw/washer combination must be replaced with a larger washer to help ensure the old washer indentation does not affect the new adjustment. 2. Attach the right adjustment tool to the right end of the mechanism as follows:
A. Align the fixed and spring loaded posts on the right adjustment tool with the two holes on the right side of the mechanism, just below the carriage rod tip. B. While pushing the spring loaded post, mount the right adjustment tool on the right side of the mechanism. Then release the spring loaded post.

Calibrating the Banner Printer Feature
Ensure that the printer is connected to the computer's printer port (LPT1 or LPT2). 1. Turn on the printer. 2. Ensure the banner lever is set to the cut-sheet (left-most position). Note:
The Banner Lever must be in the Cut-Sheet position before proceeding. Otherwise, the printer will become misaligned and banner paper will not be picked.
3. Press the "Run" button in the "Printer Utilities" section of the DeskJet Online Service Manual to send the banner calibration file to the printer. 4. Wait until the printer completes the calibration routine and prints the slightly modified Diagnostic Test. 5. Observe the Pen State value on the Diagnostic Test printout: Pen State: Steps to bump: xxx The number should fall within the range of 140 - 230.
Troubleshooting
1. If the number is less than 140, verify that the banner lever is positioned all the way to the left. 2. If the number is greater than 230, verify that the p |

Pen state: Steps to bump: xxx
The number should fall within the range of: 140 - 230.
Troubleshooting
1. If the number is less than 140, verify that the Banner Lever is positioned all the way to the left. 2. If the number is greater than 230, verify that the Pivot Assembly installed is correct for the printer.
Optional Methods of Sending the Calibration File to the Printer
In addition to being able to send the calibration file from the DeskJet Repair Reference, you can also send the file to the printer from a separate Banner Calibration disk. Use one of the following methods to send the Banner Calibration file from a disk. DOS: Use the binary copy command to send the file to LPT1 (or LPT2). For example:
