File name ADJ6XX1.PDF Adjustments HP DeskJet 6xx Printers 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. Paper Guide - Fixed Carriage Rod - Adjustable at Each End 2162630 PPS - Pen to Pivot Spacing Pivot - Rotation Limit Determines PPS and Paper Guide to Pivot Gap Paper Guide to Pivot Gap Figure 1.Description of Adjustment Checks Adjustments - Overview 1. Checking the Pen-to-Pivot Spacing (PPS) The pen-to-pivot spacing (PPS) verifies the proper distance between the pen (PPS Measure Tool) and the pivot cockle ribs. 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 the PPS into tolerance by first setting the pivot rotation limit using the pivot adjuster. If the spacing cannot be obtained by the pivot adjuster, then adjust the carriage rod by installing the carriage rod adjustment tools on both ends of the mechanism. 2168920 Figure 2. Adjusting the Pen-to-Pivot Spacing with the Pivot Adjuster Adjustments - Overview 2. Checking the Paper Guide-to-Pivot Gap With the pen-to-pivot spacing between 28 and 58 mils, check the paper guide-to-pivot gap. The paper guide-to-pivot gap determines the distance between the paper guide (which is fixed) and the pivot when in the normal printing position (printing on paper and transparencies). A shim is placed between the paper guide and the pivot. The difference between the reading on the Readout/Controller with the shim in place and removed should be between 15 and 35 mils. If the difference is less than 15 or greater than 35 mils, rotate the pivot adjuster to bring the difference between 15 and 35 mils. Note Adjusting the paper guide-to-pivot gap affects the pen-to-pivot spacing. Check the pen-to-pivot spacing after any paper guide-to-pivot gap adjustment. 2168905 Figure 3.

File name ADJ6XX5.PDF Adjustments HP DeskJet 6xx Printers 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. HP DeskJet 6xx Printers - Adjustments (Adjusting the Carriage Rod) 1 Note: You may need to turn the micrometer knob in order to have both posts (fixed and spring loaded) align with both holes on the side of the mechanism. Note: If the tool is properly mounted on the mechanism, the spring loaded post will remain depressed once you release the post. 3. Remove the rod retainer from the left end of the mechanism. Note: A misaligned adjustment tool could damage the mechanism. To avoid this, verify that the bracket screw on the left side is already loose. If not, loosen the screw now. 4. Attach the left adjustment tool to the left end of the mechanism as follows: A. Align the left adjustment tool over the left edge of the mechanism. B. Lower the left adjustment tool such that it straddles the left edge of the mechanism. HP DeskJet 6xx Printers - Adjustments (Adjusting the Carriage Rod) 2 Note: You may need to turn the micrometer knob in order to have the left adjustment tool fully seat on the left side of the mechanism. 5. Lock the left adjustment tool to the left side of the mechanism. 6. Install the LVDT. 7. Lift the envelope sensor on the mechanism to raise the pivot to its maximum height. HP DeskJet 6xx Printers - Adjustments (Adjusting the Carriage Rod) 3 Note: Make sure the envelope sensor remains raised during this entire procedure. 8. Slide the LVDT over the left paper feed roller. HP DeskJet 6xx Printers - Adjustments (Adjusting the Carriage Rod) 4 9. Adjust the left end of the carriage rod by turning the mircometer knob on the left adjustment tool. The Readout/Controller should display between 028.00 and 058.00 mils (nominally 040.00 mils). 10. Slide the LVDT over the right paper feed roller. 11. Adjust the right end of the carriage rod by turning the micrometer knob on the right adjustment tool. The Readout/Controller display should read between 028.00 and 058.00 mils (roughly the same as step 10). HP DeskJet 6xx Printers - Adjustments (Adjusting the Carriage Rod) 5 12.

File name ADJ6XX6.PDF Adjustments HP DeskJet 6xx Printers 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 pivot assembly is installed correctly in the printer. Other Methods of Sending the Calibration File to the Printer Note: The below examples assume the file "CAL.PCL" is on a disk in drive A:. From DOS Use the binary copy command to send the file to LPT1 or LPT2. For example, COPY /B A:\CAL.PCL LPT1 {Enter} From Windows 3.1 You may use the MS-DOS prompt and proceed as above, or select "File Manager," and select the A: drive, highlight CAL.PCL, select "File," then select "Copy." When prompted "Copy To:" enter LPT1 or LPT2, select "OK," then select "Yes." From Windows 95 Select "MS-DOS" prompt, from the "Programs" menu. Proceed as you would DOS (see above).
