I'm a lead technician for a company that produces and services large copier/printers, and they while they do suck, they are far better than garbage tiny printers. Mostly because they cost between 10k-100k so actual engineering went into them.
The best advice I can give anyone is if you need a low volume machine, buy a laser Brother and throw it away when it breaks. If you need occasional color, go to Kinkos. If you need high volume, go lease a machine from a company and let the tech handle things.
Edit: There is nothing that is more wasteful and dumb than every person in the office having their own small printer.

That is amazing, I am/was(it is complicated) a lead senior tech for a photocopier company. I didn't realize there were so many of us on SA. I work for an OEM but it isn't Xerox.

Consumer grade printers are bad because they are made as cheaply as possible. It is as simple as that.
Office/Production printers are usually far higher quality and are much cheaper per copy, but your average person has no use for/can't afford one.

I've outed myself as a Xerox engineer but out of all of our kit out there I work on, the only machines I've had no real mechanical problems on are the 712x, 722x and 53xx machines they tend to have electronics that fall over on the reg but the motors, clutches & drives just seem to go forever. I've currently kicked a Versalink C7025 which is new on the market up to national tech support because for reasons I cannot fathom it's skewing out of the second tray and second tray only, despite all of the motors and gears being fine, and the feeders and rolls being replaced. I think it's an internal setting to do with the torque being applied when it pulls the paper through but gently caress going through the thousands of internal settings to figure out which one it is.

Have you tried different sizes/orientations of paper? The color mid speed models we released recently have an issue with feed on DLT, has to do with a lack of support on the non-feed side, lets the paper wiggle back and worth and causes skewing and wrinkles.

yup, tried the same ream of paper, landscape and portrait in all four trays and tray 2 was the only one that was jamming. Tried a fresh ream from a different box and that jammed from tray 2 only so it's been escalated for someone else to have a crack at

edit: wait, the only thing I didn't change was the tray itself. Maybe the lifting plate was warped and that was causing the clash as it fed. gently caress sake

Don't forget the tray 2 feed station, the portion that actually grabs the paper. I have found bad units by swapping the feed station between trays and having the issue follow the feed station. Could be as simple as a bad photosensor.

I replaced the feedhead and takeaway roll, and I think that for whatever reason the motor's supply too much torque on tray 2 and only tray 2 that it's causing the paper to smash on the way out, as the paper from trays 3 & 4 has to feed out from the same path and goes through fine. I mean, it's not as bad as a 58xx which was jamming from the far tray of a tandem tray unit, and by jamming I mean a random dog ear from a particular paper type and from a particular tray and replacing every single piece that the paper could touch on the way through to the finisher didn't get rid of it. The paper type would print fine from trays 1,2,43, the bypass and tray 6, but the second it was loaded in tray 3 (which I think has the furthest to travel on those machines) it would randomly dog-ear then misstack in the finisher. After four visits (including an aborted visit where my overnight from the Netherlands order of parts turned out to be a ripped and therefore empty plastic bag that was supposed to contain a bearing), me and the national training guy just agreed to bin the thing

Heh, had that happen a few times when I escalate the call to engineering and they decide it isn't worth the effort. Like the production machine that would blow a board whenever you closed a particular tray. After replacing that board 5-6 times, the national guy just decided to replace the machine as that would cost less than continuing the troubleshooting.

Trip report: Papercut is amazing and if you manage more than 3 printers get it. That is all.

We sell like 20 varieties of Papercut, Equitrac, Autostore, etc, they are all pretty much the same in the end. The hardest part is getting the customer to pay for it, followed closely by most customers having garbage slow networks and IT infrastructure making deployment and operation a pain.

I've not been at work today, so when I turned my phone on I got a barrage of text messages from an unknown number asking if I'd look at their 7535 I'd looked at at some point earlier this year. They started out friendly enough, but the last one basically said "WELL WHAT WAS THE POINT OF GIVING ME YOUR NUMBER IF YOU WEREN'T GOING TO HELP?" I love my job

Never give your number to customers. I took it off my business card 8 years ago and I still get random phone calls.

Just had a call diagnosing an issue with fax forwarding that had been escalated to me after multiple techs and IT people couldn't fix the issue. The fix? Customer didn't whitelist the copier IP address in their relay server.
Ugh. Now to go rebuild some developer units because my position has me literally doing 3 people's jobs.

I am currently working as back office staff for a small clinic and have some money to upgrade our printers. Currently in addition to a large monochrome fax/copier/bulk job printer we have THREE printers in the back office: a small monochrome laser that isn't even hooked up, a mid size monochrome laser with two trays that is the primary printer both on plain paper and special prescription paper, and a mid size fax/copier/printer that is literally only used as a black and white copier.

As part of my job I am producing nice materials for our patients that include things like information sheets, patient calendars, etc and we are going to get a color laser printer to help facilitate this. It would be nice to get a multifunction and replace the other three back office printers but that is not required. Budget is under 750, ideal stats would be: at least 2 trays and a multipurpose tray (to cover regular paper, order paper, and cardstock/high gloss paper for making nice handout materials), ability to handle up to like 170 gsm paper, automatic duplexing, network connectivity, and copying capability. Brother, OKI, HP, Cannon all make printers that fit this description but I have literally never bought a printer in my life, much less one designed for small business use, and I'm not having a lot of luck finding great comparative reviews. Anyone have any experience with this kind of purchase?

Lease a small color MFP from a dealer, and if you are going to run that heavy stock make absolutely certain you set the media weight correctly. Modern printers use lower temperatures for energy efficiency and the trade off for this is that if you don't set the proper media weight it will not fuse correctly and/or destroy the fuser.

So we know it isn't a motor or sensor issue because it works occasionally, unless the sensor has paper dust on it. It is unlikely to be paper, but it is possible. I'd say the most likely fix is replacing the feed assembly rollers with a new set, and not grabbing random ones off another model of printer.
Also Brothers are solid machines but very disposable, so it might just be time to drop it in the garbage and get a new one.

Speaking of budget printers from 2006, are the different toners (like the actual powdery black stuff) similar enough be used across brands?

No. Toner is radically different between brands. It has to do with the particle size, the chemical composition, and how the charge is intended to work.
It might work for a bit but it will probably destroy your printer.

As a professional printer toucher, I need to know which way your paper is feeding to properly diagnose your issue. Landscape or portrait?
Also the cost is 275/hr with a 20 dollar materials fee

If it is literally feeding the short edge, then it is a very weird issue. But if it is feeding the long edge, I'd bet the drum charge roller is dirty and is causing the yellow line, and the black stuff is likely fuser related, with a possibility of the black drum having an issue. You can be certain if it is the drum or fuser by printing a few solid magenta or cyan prints. If the black ghosting stays the same color it is drum, if it changes to the printed color it is fuser.

Now I'm not an expert on this particular model of printer, but on any of my machines I'd suspect the itb(internal transfer belt) cleaning unit. If you get ghosting from literally every color it is the most likely option. Your fuser looks perfect and your drums look like crap(especially yellow which is where that line is coming from) but the ghosting is very likely to be the itb cleaning unit. I'm bored so I'm gonna look up your model and then update this post after I find out how your printer cleans the itb.

All printers/copiers should have a interlock switch on any covers that lead to major components for the sheer possibility that someone takes a laser in the eye and immediately goes blind. Like, no joke, you'd be blind in that eye permanently. Oh, and the lasers are invisible to regular sight, so fun times.
On my equipment the interlock cuts all power to 24v, leaving only 5v operational.

Actually the more important reason is that color laser copiers/printers are constantly running calibrations and adjustments between jobs to stabilize the toner density. These calibrations require all toners to be available.

Okay, but isn't that by design? If mixing all four toners makes a blacker black, why not mix all four toners in one cartridge and make that the new black toner?

That isn't how it works. Also, the industry calls this 'process black', and by itself it looks like poo poo. The idea is the you put a thin layer of the other colors on top of black to increase its density, making it look more 'black'. It also isn't used by default for all vendors, as for my company it is an option but not one we normally enable.
