hp laser printer repair group?
¿ªÔÆÌåÓýYou are sooooooo correct. ?But if you want to, get a bottle of fedron AKA Dr. Scat, or rubber roller restorer it really helps on the rollers. ?Don¡¯t use compressed air always suck, the dust is sort of conductive. ?We used full strength di-Limonene (they use a bit in Simple Orange) to clean everything. Upside it really cuts the pine resins and doesn¡¯t hurt anything downside you have to use 409 (or similar) to clean off the sticky residue. ?Besides that we always got compliments on how nice the room smelled when we left.?Good luck!

HP laser printers all use a Canon print engine that HP wraps its own plastic and personality board around.

So the "consumable" rollers, separation pads, fuser parts can all be sourced easily. There are a number of vendors out on the web that sell the parts.... On Wednesday, October 7, 2020, Stephen Hanselman <kc4sw.io@...> wrote:

Do the others work as well as Fedron? The other cleaners/restorers have different chemical ingredients. Years ago, I heard something bad about Fedron (can't remember... maybe its was carcinogenic?)... or for some reason we couldn't buy it in the colonies...at the time. The printer techs loved it, but were down to secreting bottles of it in their kits. Maybe they changed the chemical composition of Fedron? On a more picayune note, its D-Limonene (for Dexto Limonene, the biologically preferred enantiomer of the molecule.) |

I've owned and maintained many printers over the years, and found that it's a crap-shoot finding detailed info about the innards. There's some stuff out there on various makes and models, sometimes found in discussion groups, or from people that sell the inks and toners and such. After enough experience and disappointment with HP, Epson, Canon, et al, I long ago decided that Brother brand printers were the best for low cost, long term reliable running, and maintenance. They have been my favorites for at least a decade, and the only brand I would buy.?
About a year or so ago, my old HL-4040CN color laser crapped out, with some error code indicating the problem. It turned out that I had a pdf of the entire factory/shop service manual (several hundred pages) for it, that I had stumbled upon years earlier, while looking for something else. I dug up the manual, and determined that the laser scan motor had seized up. The manual has all the info needed to diagnose and take everything apart and replace modules, but I went a step beyond - I took the motor apart, cleaned it out, re-lubed the bearing, and it was back in business. I think normally, the entire optical scan unit (probably more expensive than a whole new printer) would have to be replaced. More recently, it crapped out again, this time due to failures in the belt unit and other disposables. I can't really complain about this, since these consumable parts had never been replaced, and had run way past their normal life expectancy. At this point in the life of a printer, you have to weigh the cost of the replacement items versus getting a whole new printer. I decided to retire the 4040 and junked it out, even though it probably could have gone for a few more years. In its place, I have parked a HL-3040CN of similar vintage, that I've kept in reserve. When this one craps out, I'll get a brand new Brother whatever color laser. I don't know if I'll find a manual too - I guess I'll see when I get there. Anyway, luck with keeping printers going and finding info is very variable, but since they have become such commodity items, it's not a big deal to attempt simple repairs even without much info to go on. There's not that much to lose if you make it worse. Sometimes even banging on stuff - like the the old TVs from way back - can make a difference. Ed |

LOL at your last statement, Ed!? Shake that toner loose! Years ago I worked at a start-up company that had an HP laser printer.? It worked fine, but I think the paper bail came apart.? One of our technicians was pretty handy, and he bolted it back together with some nuts and bolts we had lying around.? AFAIK, it was still running fine when that company bit the dust (a whole story in itself) about 15 years ago. Jim Ford
