printer pick-up roller replacement sources
Hi,
I have several laser printers (TI Microlaser pro 600) and a pile of brand new consumables for said printers. The printers are unusable because the pick-up rollers for the upper and lower paper trays, in all of the printers, either misses the paper entirely or jams at the input. Otherwise, the printers are in fine condition and worked with no problems until they were retired. Acetone is supposed to restore marginal rubber as a temporary fix, but these rollers are very difficult to access, so a temporary fix would be more trouble than it's worth. I am having an unusual amount of trouble locating parts for these printers. TI/Genicom never replied to my email request. Fixyourownprinter.com carries an *exit* roller, but it just happens to be an exact equivalent to an exit roller that another manufacturer supplies. I can't find anyone who will sell me pickup rollers. So if anyone knows of a supplier for this part, please let me know. Another thought I had is that perhaps the rollers can be re-lined with fresh rubber in a generic fashion. But I don't know what such a process would be called, and am even more skeptical that it would be economical in single digit quantities. (I have six bad rollers in all.) However, if someone could manufacture a replacement based on a few failed samples, I'm certain it could be stocked in quantity by at least one vendor. I *hate* to throw these printers away especially with all the brand new toner that came with them. But if replacements for whatever rubber parts are in it are not available, I guess there's very little choice with any machine, isn't there? A new corollary to the electrolytic capacitor axiom. |

I wouldn't consider this except as the very last resort, immediately before hauling them to the dump, but... I've had a bit of luck with old irreplacable capstan idlers (old ampex reel to reel stuff) giving them just the gentlest of sanding with a fine grit sandpaper. Remove just enough to take away the glaze and discoloured rubber, and expose nice fresh black stuff. It seems that removing the outermost "dead" layer of rubber exposes new, better stuff underneath. Take care. Ken |

Have you tried wetting the rollers with a damp soapy cloth? When I encounter a problem with HP printers failing to grab a sheet of paper, I wet a small cloth and apply dish soap to it. Pressing the line feed button to make the roller move while holding the soapy cloth so that the roller surface gets wet, will solve that problem. You might try it on your printers. |

I got this stuff ages ago, so doubt its still being made (do they make VCRs anymore?) Bill, KB8EB |
Sometimes it's not the pickup rollers but the paper tray springs loose the
oomph! remove the tray, if you can and stretch those springs so they push that paper UP "Ryan Underwood" wrote in message ...

To the OP: if you're going to try some solvent on the rollers, the easiest way to get it on them will be to put some on a piece of paper and send it through. If you want to try sanding them, send a piece of pretty fine sandpaper in and hold it so the rollers spin on it a little, then pull it back out. I'd not use anything coarser than about a 120 grit, maybe a little finer than that. John |

Given that the "sanding" suggestion originally came from me, I'd respectfully suggest re-thinking sanding the rollers while they're still in place in the machine. I'd be wondering where any grains of sand from the paper might end up... along with any tiny bits of removed dead rubber might go... For my nickel, I'd much rather remove the roller first, clean it thoroughly before re-installing it. Just a thought... Ken |

[TI Microlaser Pro 600 bad pickup rollers] Another thought I had is that perhaps the rollers can be re-lined with fresh rubber in a generic fashion. All tape machines have a pinch roller somewhere in the tape path. (On 8-tracks it's in the cartridges instead of the machine, but it's there.) These are a common replacement part. Depending on how big the rubber areas on the printer rollers are, perhaps you could substitute the "skin" of a new pinch roller. Places with VCR parts (MCM Electronics?) might be the best place to look for replacement pinch rollers. If you can find sheet rubber of the right consistency, you might be able to cut strips of it and wrap it around the pickup roller, securing it with glue. This might cause problems if the seam catches the edge of a piece of paper, though. Matt Roberds |
I am curious if you tried calling the authorized TI repair servicers
for the parts? Most times with business equipment, you cannot buy from the manufacture direct, but have to call a business products dealer/servicer. |

Bill, KB8EB I used to have a bottle of 'rubber belt rejuvenator', It worked very well on vcr pinchrollers and the like. The wholesalers stopped selling it as they said it was classed as hazardous. At the time my next door neighbour was a chemist, he took a sniff and pronounced it xylene, Hazardous when inhaled, and disolves many plastics.

I guess I'll look around for one that has an online presence then. |

I was under the impression it softens the rubber. With time, rubber such as this gets hard, and that's a problem. They'd have these mixtures to soften it. From what I've read, the same sort of thing applied to the platens of typewriters, and the stuff was available for that, too. Michael |

On a related note, my father used to do offset litho printing - one of the substances used in that was sold as "blanket rejuvenator" by some companies - the blanket of the machine is made of rubber - and under its chemical name by others - MEK, otherwise known as butanone! That's good provided it doesn't attack what you're working on, but it is noted to be highly flammable and extremely volatile, so great care would be needed if you tried that. We also had some "blanket reviver" which was 1,1,1-trichloroethane. It didn't prove that useful. -- Phil Reynolds mail: (though I'd prefer followups on group) Web: http://www.tinsleyviaduct.com/phil/ Waltham 67, Emley Moor 69, Droitwich 79, Windows 95 |

Ron- That is my understanding of how the rollers stop working. The plasticizer is absorbed by the paper. Another approach is to apply a plasticizer to the rollers, replacing that which has leached out. Some chemicals used to restore plastic dashboards and seat covers in cars, as well as to shine-up tires, may be such a plasticizer, and should work to rejuvenate printer rollers. Fred |
