HP DraftMaster Plotters - Error Codes and Failures

X-Axis Failure

ISSUE: Conditions causing an X-Axis Failure message to appear on the front panel of an HP DraftMaster family plotter.

SOLUTION: There are three conditions that may cause an X-Axis Failure to occur:

  1. Paper jam or other mechanical binding of the grit-wheel drive.

  2. Defective X-motor/encoder.

  3. Defective Analog and/or Processor PCA board.

If paper is visibly jammed in the grit wheel or rollers, removing the obstruction may alleviate the problem. If receiving this error and it is not caused by a visible jam, contact an authorized service dealer for repair.

Y-Axis Failure

ISSUE: Conditions causing a Y-Axis Failure message to appear on the front panel of an HP DraftMaster family plotter, and how to alleviate the problem.

SOLUTION: Three conditions exist that may cause a Y-Axis Failure to occur:

  1. Mechanical binding of the pen axis drive mechanics.

  2. Defective Y motor /encoder.

  3. Defective Analog and/or Processor PCA board.

If the pens are blocked or jammed by visible obstruction, removing the obstruction may alleviate the problem. Also, if the pens are jammed in the carousel or loaded improperly, removing them and replacing them properly may solve the problem. If the above does not solve the problem, the plotter will have to serviced. Refer to the closest HP service center.

Z-Axis Failure

ISSUE: Conditions causing a Z-Axis Failure message to appear on the front panel of the HP DraftMaster family plotters, and how to alleviate the problem.

SOLUTION: There are four conditions that may cause a Z-Axis Failure to occur:

  1. The metal-tipped pen carriage probe is too close to the media surface during a pen down operation (pen installed). This can occur if the pen adapter is not screwed tightly to the drafting pen body or if the pen tip has been excessively worn down. This failure can also occur if the plotter performs a pen-down operation without a pen installed in the pen carriage.

  2. Defective pen carriage.

  3. Defective trailing cable.

  4. Defective Analog and/or Processor PCA board.

Try replacing the pens. If this does not work, have the plotter repaired.

"Check Pen and Paper"

ISSUE: Existing conditions that may cause a "Check Pen and Paper" message to appear on the front panel of the HP DraftMaster family plotters.

SOLUTION: Five conditions exist that may cause a "Check Pen and Paper" error to occur:

  1. Excessive wear of pen tip.

  2. Drafting pen adapter not screwed on.

  3. Pen fell out of pen claw.

  4. Torn media.

  5. Plotter needs mechanical calibration. An authorized service dealer should service the plotter.

Media Load Problems

ISSUE: Solving media load problems in the HP DraftMaster family plotter.

SOLUTION: Incorrectly loaded media may be crumpled or may fall out of the plotter when the plotter tries to determine media size. The display on the front panel may also indicate an X- or Y-Axis failure.

To solve media loading problems:

  1. Turn the plotter off.

  2. Allow the media to stabilize to the plotting area's temperature and humidity before using.

  3. Remove any currently loaded media (including torn scraps) and then load a new, unwrinkled sheet of media.

  4. Align the right side of the media with both the front and rear paper guides, making sure that equal lengths of the media are hanging out both sides of the plotter.

  5. Align the white arrow on top of the left pinch wheel with the left side of the media.

  6. Lower the pinch wheels completely.

  7. Turn the plotter on.

  8. If the problem persists, have the plotter serviced.

ISSUE: The plotter fails to move the media back and forth to check its size and alignment when the lever and cover are lowered.

SOLUTION: Follow the above procedure. If the problem still persists, have the plotter serviced.

NOTE: * Some error codes are explained in detail below the table.

Error 6 : Position Overflow, indicates that an overflow occurred after an internal calculation was performed.

Error 7 : Buffer Overflow, indicates a graphics buffer overflow (i.e., downloadable, polygon, etc.).

Error 15 : Error in I/O Transmission, indicates a baud rate mismatch or framing error.

Error 100 : See Service Manual - Processor exception, normally caused when the instruction pointer becomes lost, an illegal opcode has been received, or an illegal memory location is accessed.

Error 200 : See Service Manual - Indicates the need for a mechanical calibration. HP recommends an authorized HP service technician perform the calibration.

Error 300 : See Service Manual - Indicates the need for an accuracy calibration. The message is displayed approximately 10 seconds and then clears. It will reappear whenever the plotter is powered on until the accuracy calibration is performed. This error condition will not interfere with plotter operations. However, the plotter may not perform to specifications.

Hardware error codes

Code
Description
00
Paper unloaded with a "PG;" command or pinchwheels raised at power-on (normal operation).
10
Right-edge sense failure. Main cause is intermittent stiction in the pen up/down axis (Z-Axis). Fix by replacing the pen carriage assembly.
11
Right-edge sense failure. Main cause is stiction in Z-Axis. Fix by replacing the pen carriage.
12,13
Right edge was found; however, media skew was detected. Probable cause - misloaded media or excessive error in the Y-Axis.
20
Left-edge sense failure. Main cause is intermittent stiction in the pen up/down axis (Z-Axis). Fix by replacing the pen carriage assembly.(fast scan)
21
Left-edge sense failure. Main cause is stiction in Z-Axis. Fix by replacing the pen carriage. (fast scan)
22
Left edge found during the second scan at an unexpected location. A tear in media may cause the plotter to incorrectly interpret as an edge.
23
Left-edge sense failure. Main cause is intermittent stiction in the pen up/down axis (Z-Axis). Fix by replacing the pen carriage assembly. This code refers to slow scan.
24
Left-edge sense failure. Main cause is stiction in Z-Axis. Fix by replacing the pen carriage. This code refers to slow scan.
25,26,27,28
These four codes indicate the left edge was found in a non-grit wheel area.
30
Front-edge sense failure. Main cause is intermittent stiction in the pen up/down axis (Z-Axis). Fix by replacing the pen carriage assembly. (fast scan)
31
Front-edge sense failure. Main cause is intermittent stiction in the pen up/down axis (Z-Axis). Fix by replacing the pen carriage assembly.
32
Front-edge sense failure. Main cause is stiction in Z-Axis. Fix by replacing the pen carriage. This code refers to slow scan.
33
Checked the right edge after finding the front edge and determined an excess skew existed. Typically caused by improper alignment of the right edge of the media with the front and rear paper stops.
40
Rear-edge sense failure. Main cause in intermittent stiction in the pen up/down axis (Z-Axis). Fix by replacing the pen carriage assemble.
41
No media present.
42
Rear-edge sense failure. Main cause is intermittent stiction in the pen up/down axis (Z-Axis). Fix by replacing the pen carriage assembly.
43
Rear-edge sense failure. Main cause is stiction in the Z-Axis. Fix by replacing the pen carriage. This code refers to slow scan.
44
Roll feed supply roll out of media.
