Clean HP Designjet 800 Printhead

     How to Clean the HP DesignJet 800 Print heads

HP Designjet 800 series 24- and 42-inch wide printers provide business and technology professionals with high-resolution, large-format inkjet printouts including schematics and plans, line drawings and illustrations, presentations and posters. Over time, the Designjet 800 printheads and print head carrier electrical contacts will become dirty with dust, paper particles and other debris resulting in reduced print quality including blurry or light images and void spots. When this happens, you must remove the print heads and wipe away the debris to improve printer efficiency.

Instructions

  1.      Turn your HP Designjet 800 printer off. Turn it back on again and wait for it to finish initializing.
  2.      Press the “Down Arrow” key to highlight the double ink drops on the right side of the display that represent the “Ink” menu. Press the   “Enter”    key to access the menu.
  3.      Go to “Replace Print heads” on the display using the “Down Arrow” key. Press the “Enter” key. Lift up the top cover and then the carrier cover.
  4.  Lay a large piece of paper on a nearby counter or tabletop. Remove a print head from its carrier slot and lay it on its side on the paper. Repeat with the other print heads.
  5. Unplug the power cord from the back of your printer.
  6.  Wipe the electrical contacts on the print heads and carrier slots with a slightly damp coffee filter or lint-free cloth to remove the dust and other debris.
  7. Insert the print heads back into the carrier — making certain that the color displayed in each slot and the color on each print head label matches. Lower the carrier and top covers.
  8. Connect the power cord and check that you have plain paper or HP Bright White Inkjet (Bond) Paper, HP Coated or Heavyweight Coated Paper, HP High-Gloss Photo Paper or HP Satin Poster Paper — loaded in the printer. Turn on the printer and wait for the printer to prompt you to align the print heads.
  9.  Scroll to the “Ink” menu icon using the “Down Arrow” key and press “Enter.” Scroll to “Align Print heads” and press “Enter.” Scroll to “Standard” if prompted and press “Enter” to start the alignment process.
  10. Wait for the process to end in approximately 4 1/2 minutes and the printer to prompt you to run the color calibration procedure. If the paper loaded in the printer is different than the type used the last type you calibrated the printer, load the type used before. Select the “Ink” menu again, select “Color Calibration” on the menu and then select “Calibrate Paper.” Wait for the procedure to end and then begin printing your projects.

 

HP LaserJet 4300 Printer- Grinding Noise

HP Laser/LaserJet Printer 4200,4240,4250,4300,4350,4345mfp repair with loud grinding , knocking noise & jamming in Los Angeles, Orange County, Riverside and San Bernardino

Problem:

 

Loud Grinding Noise issue HP Laserjet 4200, 4240,4250 4300,4350,4345mfp

Overview

1.Paper jam – If the gears don’t engage at all, the fuser roller will not turn. When paper reaches the fuser, a paper jam will occur.

2.Grinding noise – If the two gears engage improperly, a grinding noise can result, which can also cause damage to the fuser gear, the swing plate gear, or both.

A known issue with the HP Laserjet 4200, 4240, 4250, 4300, 4350 & 4345MFP
is a noticeable grinding noise.  The issue is caused by the HP Laserjet printers
fusing assembly and the Laserjet swing plate Assembly not correctly engaging each
other due to worn gears.  When the Laserjet printer gears become worn they will not
correctly align and you will start to hear a grinding noise from the back side
of the printer.  Delays with repairing of printer will result in continuous
paper jams and an eventual total failure of the Laserjet printer.
 

Solution:

Replacing the fusing assembly and the swing plate gear assembly will
correct the grinding noise.

HP LaserJet 4000, 4050, 4100, 4200, and 4300 Series Printers – Diagnosing and Repairing Abnormal Printer Noises

Printer noises coming from the HP LaserJet 4000,4050, 4100, 4200 or 4300 series printers can be described as high-pitched or ultrasonic sounds such as ringing, humming, or whining. Other descriptors include squeaks, groans, moans, rubbing, clicking, fluttering, or rattle.

Noises can be caused by a number of things, some of which may not be addressed in this document. This document deals strictly with the isolation and potential resolution of known noises through troubleshooting.

 

NOTE:

Feed/separation roller groan may be associated with a 13.1 error message.

 

 

 

 

Normal noises

Fans will come on during power up, printing, and will stay on for a short time after printing. On the HP LaserJet 4100 series printers, the fan will turn on and the main motor will rotate periodically while in Power-Save mode or Ready mode.

During printing, it is not uncommon for a high-pitched, ultrasonic whine to be noticed by those individuals with extremely good hearing or audio augmenting devices such as head-sets, hearing aids, etc.

The laser scanner will produce a sound similar to that of a vacuum or a jet engine powering up, sort of a whooshing sound that increases in pitch.

 

NOTE:

At low levels, this is normal. It can become too loud, indicating that it may need replacement.

Instructions

 

Noises can be difficult to isolate. Noises are very subjective and awkward to describe, therefore, user descriptors can differ and the only accurate way to determine the origin of a noise is to isolate the issue using the following troubleshooting, in order.

Troubleshooting:

Additional information:

1. Does the noise occur during power-up?

1.1. Check that any installed accessories and consumables (duplexer, envelope feeder, fuser, or toner cartridge, etc.) are installed correctly by reseating them and then power-cycling (unless performed during a previous step).

If the noise does not go away, remove the accessories and consumables, one at a time, to determine if the noise is associated with one, or a combination more than one, of them.

1.2. If the noise goes away with the toner cartridge removed (or the fuser, or the transfer roller), it will need to be replaced.

1.3. If the noise does not go away with the toner cartridge removed, remove the transfer roller. If the noise goes away with the transfer roller removed, it will need to be replaced. If the toner cartridge is near the end of its expected life (6,000 pages for standard cartridges, 10,000 for extended use cartridges), the consumer will be responsible for replacing it.

1.4. If the noise does not go away with the transfer roller removed, then the noise may be associated with an internal component.

1.5. If the noise still hasn’t been resolved, please refer to number 7 in the troubleshooting column.

2. Remove the printer from any UPS (uninterrupted power supplies) or power strips and plug directly into an outlet.

2.1. If the printer is plugged into a UPS, a beeping or whistling noise may be coming from the UPS. Plug the printer directly into a wall outlet to eliminate the possibility of power issues caused by other power devices.

3. Is the printer able to print?

3.1. If the printer is unable to print, did a paper jam occur, and then the noise? Paper jams can keep the printer’s internal components from moving, creating unusual noises.

3.2. If there is a paper jam, where is the leading edge (the edge of the paper that entered the printer first) located?

3.3. Does the jam (and noise) occur in the same location, each time? If so, is it related to a particular tray?

3.4. Attempt to print an event log (view it on the printer display, if unable to print), making note of the error codes listed.

4. Was a consumable recently replaced?

4.1. If a consumable was recently replaced, it could be improperly installed or defective.

4.2. Open the Top Cover, remove the toner cartridge, turn the printer off, and then back on again. If the noise still occurs, the Toner Cartridge and Transfer Roller can be eliminated as the source of the sound.

4.3. Exchange the consumable with a known good or new consumable, preferably the HP brand to determine if the noise was associated with the consumable.

5. Was an error displayed on the printer when the issue occurred?

5.1. Error codes can also be a clue to the source of the noise. Make note of the error code to use for future troubleshooting.

6. Does the noise occur during power-up?

6.1. Check that any installed accessories and consumables (duplexer, envelope feeder, fuser, or toner cartridge, etc.) are installed correctly by reseating them, turning the printer off, and then turning the printer back on again (unless performed during a previous step). If the noise does not go away, remove the accessories and consumables, one at a time, to determine if the noise is associated with one, or a combination more than one, of them.

6.2. If the noise goes away with the toner cartridge removed (or the fuser, or the transfer roller), it will need to be replaced. If the toner cartridge is near the end of its expected life (200,000 pages), the consumer is responsible for replacing it.

6.3. If the noise does not go away with the transfer roller removed, then the noise may be associated with an internal component.

6.4 If the noise still hasn’t been resolved, please refer to Step 8 in the troubleshooting column.

7. Does the noise occur during printing?

7.1. Print to the top output to isolate a squeaking sound.

7.1.1. If the printer squeaks, open the rear door and print.

7.1.2. If the squeak disappears or lessens considerably when printing to the rear output, then replace the delivery assembly. Verify that the issue has been corrected by printing a test job to the rear output.

7.2. Print from Tray 1 to determine if the sound is coming from there.

7.2.1. Continue with the next step if the sound is not produced when using Tray 1.

7.3. Print from Tray 2 to determine if the sound is coming from there.

7.4. If the sound originates in Tray 2, then continue troubleshooting with Step 7.5 to continue isolating the sound.

7.4.1. If the sound does not originate from Tray 2, print from Tray 3.

7.4.2. If the sound originates in Tray 3 and/or 4, then repeat the steps in sections 4.0 through 6.0.

7.4.3. If the sound does not originate in Tray 3, then contact Hewlett-Packard for additional support.

7.5. Visually inspect the feed/separation rollers for Tray 2.

7.6. If the sound continues, exchange the feed/separation rollers in Tray 3 (if possible), with the rollers from Tray 2
7.7. If the sound follows the rollers, then print a Configuration page. The consumer will need to order the maintenance kit if the page count on the Configuration page is close to 200,000 pages and install maintenance kit.
7.8. If the sound does not follow the rollers, and was not resolved by the previous troubleshooting steps, then the pick assemblies for the trays in question will need to be replaced.
