Hewlett-Packard LaserJet IIISi

IRREGULAR PRINT

Any irregularities such as white streaking on one side can be eliminated by removing the toner cartridge from your printer and rocking it gently 5 or 6 times to evenly distribute toner. If this does not improve print quality, call Pendl Company at 1-800-236-2000 for assistance with a replacement toner.

LIGHT PRINT

Use the green lever, located inside of the printer on bottom left side, to increase print density by following the diagram included with your toner cartridge.

Replacement EP-N toner cartridges are available for your Hewlett-Packard LaserJet IIISi printer from customerservice@pendl.com.

WHITE STREAKING

Persistent white streaks that stripe your printed documents are not only annoying, they mar your professional appearance. This type of streaking can be caused by one of several problems. The following checklist covers all the possible causes and will help you diagnose which one is affecting your printer:

# 1: Faulty Fuser Assembly

To check for a faulty fuser assembly do the following. Open the clam shell cover of the printer. In the back of the printer is the fuser assembly unit. The green part of this unit on the back portion of the fuser will open.

Remember the fuser runs at an extremely high temperature. Be sure you are touching felted portions of the unit only to avoid burns. Gently push the green rear portion of the fuser unit back. Turn the printer around and look through the back. Are there visible streaks or rips in the upper fuser roller? Are there any visible bubbles in the upper fixing roller?

If any of these symptoms are present you will need to replace the fuser unit of the printer. Before you replace the unit take a page count off the printer. Your SI model printers have required "user maintenance kits" at every 200,000 page interval. If your page count is close to one of these intervals you may choose to order an entire maintenance kit since a fuser is included in the kit.

Both replacement fusers and user maintenance kits are available for immediate shipment from Pendl Company. Call Pendl Company at 1-800-236-2000 or e-mail at us customerservice@pendl.com for more information.

# 2: Cartridge Failure

To check for cartridge failure do the following. Send a page of print to the printer. While the page is going through the printer, open the printer in the middle of the print cycle while the paper is in the printing section of the printer. Carefully remove the toner cartridge from the printer and set it on a table upside down with the thinner portion of the cartridge away from you. In the middle of the bottom of the cartridge is a shutter that will pull back in your direction.

Carefully move the shutter back and look at the image placed on the photo drum. Be careful not to touch the drum, oils in your skin will ruin it. If the print is not placed properly on the drum you most likely have a bad cartridge.

Before you change the cartridge be sure that it is the problem by eliminating the possibility of beam interruption. Or if your resources provide it, trade cartridges with another SI printer and see if the problem follows the suspect cartridge.

In the case of cartridge failure, replace the toner cartridge. Both new and compatible cartridges are available from Pendl Company. Call Pendl Company at 1-800-236-2000 for assistance with a replacement.

# 3: Beam Interruption

To check for beam interruption do the following. Remove the toner cartridge from the machine. Are there any stickers that have come loose or are peeling? If so, remove the loose area of the sticker. Test the cartridge again.

If the problem persists, remove the cartridge and open the printer at a 45 degree angle. Look at the top cover on the inside and you will see a purplish mirror. Are there any foreign objects: screws, paper clips, paper scraps, etc. lodged in the area?

If so, gently remove the obstruction or arrange for a technician to remove it for you. Be careful not to nick or scratch the mirror, this could make your problem far more serious. Send a page of print to the printer to determine if you have solved the problem.

If the problem still persists, call Pendl Company at 1-800-236-2000 x103 or e-mail at us customerservice@pendl.com for a consultation with one of our technicians.

ECHOED IMAGES

Echoed images can ruin the appearance of your printed documents. Echoed images can be caused by one of several problems. The following checklist covers all the possible causes and will help you diagnose which one is affecting your printer:

# 1: Printer Density Setting

The solution to your problem may be as simple as changing your printer's density setting. To change the setting, open the cover of the printer. Inside the printer towards its center is a black metal plate just behind the transfer roller. On the left side is a sliding green knob with an upside down arrow.

If the knob is set too high, the printer may be printing too dark. This may be preventing the printer from transferring the full amount of toner off the drum, resulting in an echoed image. Lower the setting and send a page of print to the printer to determine if you have solved the problem.

If lowering the printer density setting has no effect or if print quality at this setting is unsatisfactory, trade cartridges with another SI series printer and see if the problem follows the suspect cartridge.

If so, replace the toner cartridge. Both new and remanufactured cartridges are available from Pendl Company. Call Pendl Company at 1-800-236-2000, e-mail us at customerservice@pendl.com for an immediate toner cartridge replacement. You may also order one on-line.

# 2: Faulty Fuser Assembly

To check for a faulty fuser assembly do the following. Open the clam shell cover of the printer. In the back of the printer is the fuser assembly unit. The green part of this unit on the back portion of the fuser will open.

Remember the fuser runs at an extremely high temperature. Be sure you are touching felted portions of the unit only to avoid burns. Gently push the green rear portion of the fuser unit back. Turn the printer around and look through the back. Are there visible streaks or rips in the upper fuser roller? Are there any visible bubbles in the upper fixing roller?

If any of these symptoms are present you will need to replace the fuser unit of the printer. Before you replace the unit take a page count off the printer. Your SI model printers have required "user maintenance kits" at every 200,000 page interval. If your page count is close to one of these intervals you may choose to order an entire maintenance kit since a fuser is included in the kit.

Both replacement fusers and user maintenance kits are available for immediate shipment from Pendl Company. Call Pendl Company at 1-800-236-2000 or e-mail at us customerservice@pendl.com for more information.

# 3: Paper Stock

Laser paper of certain stocks, even high-end quality paper stocks, carry a fine coat of wax. Paper with this coating often cannot handle the extreme heat of the fuser assembly in spite of their "Laser Paper" label.

Paper stock for use in your SI printer needs to withstand 310 degrees for one tenth of a second or it will leave troublesome build-up on your fuser. Try a different paper stock and print a test document of about 20 pages. The problem may dissipate.

If not, your fuser will need to be replaced. Call Pendl Company at 1-800-236-2000 or e-mail at us customerservice@pendl.com for more information.

BLOTCHES

Blotchy pages are generally caused by faulty toner cartridges dropping excessive toner. This is easily checked by simply opening the printer and looking for loose deposits of toner on the printer interior.

Cartridge vendors will generally pick up the cost for such incidents. If not, it's time to switch to Pendl Company cartridges. Our technicians our happy to assist in the removal and cleaning of toner from any of your equipment at our normal low service rates.

Bubble type blotches can also be caused by a defective cartridge. You can test for this problem by trading cartridges with another and seeing if the problem follows the suspect cartridge.

If so, replace the toner cartridge and call for a service consultation. Both new and compatible cartridges are available from Pendl Company. Call Pendl Company at 1-800-236-2000 x103.
