Question about Canon imageRUNNER 1023iF Black and White Copier
This machine has been serviced at least 8 times in the last 4 weeks and continues to jam every 5 or 6 sheets. All rollers and pickups have been replaced according to Canon.
They are now trying to tell me that it is the paper we are using, which is a Premium multi-usage, 20 lb paper with a brightness rating of 92. Only full reams are fed into the machine when paper is required.
I am fed up and expect it to be either fixed properly today or replaced today.
My questions: Any thoughts on what may be causing this continual problem, and, am I being unreasonable expecting it to be fixed properly or replaced?
Thanks for your input.
Have they tried to clean or replace the paper feed clutch? Also, do you have one or two paper trays? If you have two, did you try to feed the paper in the other paper tray? Also, try to flip the paper over, it may have moisture in it. Have you tried other types of paper? How about have you tried the manual by-pass tray? Will it feed that paper? Also, try that paper in another copier or printer, if it works, it has to be something with the copier it self. Just a note is the paper Glossy or a flat finish? Are you sure the parts were replaced? You may need to get a second oppion on the problem.

I typically use "Chux" wipes and a shop-vac to start with. The wipes wipe up and REALLY HOLD the toner & paper particles, holds 'em tighter than a Hobo does a ham sandwich...
(I'll concede to the 'by-the-book' crowd that a specific (read EXPEN$IVE) type of vacuum cleaner is recommended by HP & most other service org's. I've used my shop-vac for 12+ years and have serviced thousands of HP LJ's, CLJ's, AiO's, MFM's, DJ's, OJ's, etc. I have never lost a single printer because I didn't use the 'right' type of vacuum...)
The Chux wipes are available from PartsNow, LLC; www.partsnow.com/.
They also carry maint kits for almost every HP printer made as well as Lexmark, Canon, Xerox, etc.
I use Cooper's Platen Cleaner (PartsNow) to clean the rollers using 2" x 2" gauze squares and nitrile gloves. Fedron works well too. HP's website mentions isopropyl alcohol and water as their recommended solvents. Use waht works best for you.
Having some 6-inch long cotton tipped applicators (wooden handled single ended Q-Tips...) helps tremendously.
In conjunction with the correct service manual, (in your case, Combined Service Manual for HP LaserJet 4L / ML & 4P / MPHP Publication Number C2005-90988, August 1993), a thorough cleaning is very easy for almost anyone to perform.
PartsNow and several other websites have HP Svc Man's online for free, Google around.
A legacy utility from HP that I've not yet tried can print and cycle cleaning sheets to clean mainly the fuser, but also claims to clean rollers as well. HP printer specialists will recognize 'cleaning sheets' from HP's newer models, built in to the menu structure. The utility will allow you to do the same for older (LJ 4, 5, & 6) printers. Find it at:
Another Combined Svc Man is available as well that covers:
HP LaserJet 4 / 4M
(C2001A / C2021A)
HP LaserJet 4 Plus / 4M Plus
(C2037A / C2039A)
HP LaserJet 5 / 5M / 5N
(C3916A / C3917A / C3952A)
HP Publication Number C3916-90984 (March 1996).
As far as Scheduled cleaning, the cleverly formatted (LOL) table below lists HP's recommended service intervals. Over the years, I've found that adhering to the schedule has reduced unplanned downtime by almost 80%!!
DESCRIPTION / QTY / EST. LIFE (pages) / REMARKS
1. Toner Cartridge / 1 / 6800 (note 1) / When print becomes faint, shake cartridge to distribute remaining toner.
2. MP (Tray 1) Pickup Roller Assembly / 1 / 200,000 / Replace roller and separation pad together.
3. PC (Tray 2) Pickup Roller / 1 / 200,000 / Look for glazing and cracks.
4. Separation Pad / 1 / 200,000 / Look for glazing and grooves. Replace together with Pickup Rollers.
5. Transfer Charging Roller / 1 / 200,000 / May affect print quality and/or paper jams.
6. Fuser Assembly (115 V, 50/60 Hz) / 1 / 200,000 / May affect print quality and/or paper jams. Look for marks on rollers.
6a. Fuser Assembly (220 V, 50 Hz) / 1 / 200,000
7. LC (Tray 3) Pickup Roller / 1 / 200,000 / Look for glazing and grooves. Replace the Separation Pad.
8. Exhaust Fan / 1 / 25,000 hrs. (I've only had to replace one in 12 yrs...)
Note 1: The estimated Toner Cartridge life is based on A4 or letter size prints with an average of 5% toner coverage, and with the density setting at 3.
Best of luck,
