Re: Have Laserjets gone out of fashion?
The 4000/4050 printers were good, Maybe the 4100 too. But I think it was the 4200 or thereabouts where HP changed the fuser roller sleeve from mylar to metal. They are probably more long-lasting for general printing, but not so good when you print a lot of envelopes and get the bands on the sleeve where the edges of the envelopes have eaten-off the teflon. I found a local printer-parts company that "imported" replacement sleeves (and most all the other parts) from unknown parts of China and would sell the mylar sleeves for $25. Call HP for that and they'd say "it isn't a user-replacable part, here, buy a $200 refurb fuser assembly, that's all you can get." So we saved a lot of money over the years - the mylar sleeves would get the envelope bands after 6 months or so with heavy envelope printing, but $25 would fix them right back up.
But then HP went to metal sleeves. I could get them from the same importer for around $70, but I never could figure out how to grease them properly, and after a month or so they'd start making a horrible racket when the grease got pushed out of the way and it was metal-on-metal contact between the fuser bar and the sleeve. After that happened 3 or 4 times, I decided it wasn't worth the effort and told the users they'd have to spring for the $220 refurbed fuser from HP. I don't think the HP refurbs ever made the noise, so there was either some trick to putting the grease in, or they were using a grease that the importer couldn't supply.
We did look at the specially modified inkjets that were made to print insane amounts of envelopes. But most of them were in the $4000+ range, which was more than anyone here wanted to spend, and it seems like the print quality wasn't too great. This was back in 2001-2004, maybe things have changed now.
It's all water under the bridge now since we send our envelopes out for printing.
