The Mita 6090 was a huge turd. You had as much machine downtime involved by installing "enhancement kits" as you did when it just broke down, which was frequently.
After this past week I'm adding the Ricoh MP4000/MP5000 to this list:-
Twelve months ago I never thought you could make the NAD based 35/45 cpm engine any worse.
But they haven't half proved me wrong:-
The dev and toner has never been particularly great on this family, but this latest version is shocking,even with the Dev/Charge bias changes you are lucky if you get 50k before it overtones itself to death.
And why oh why did they put an oil web on the fuser? The 3035/3045 didn't have them and didn't particularly suffer for it. More to the point though why did they have to put such a fiddly one on when changing the web in the MP7500 is a five minute job? And why do one in three MP5000 web units have a seized alan screw so you can't get the damn thing apart without taking a hacksaw to it?
Why did they combine the PCU and Dev unit into a single unit, when all this achieves is making the tech spend another five minutes farting around over what he used to spend on a 3045.
I wish I could load every single one of these sh*tboxes into a rocket and fire it into the sun.
I HATE these also, I forgot about mentioning the NAD, but this m/c is horrendous!!!!
toshiba 3511....revolver machine duster 20 minutes to get anything apart 20 to put it together and it still doesnt work repeat ive gotten good at the but ive wasted so much time on them
Does anyone remember the old 3M thermal copiers that used pink onion skin paper layed over the thermal paper that ran at a top speed of 3 minutes per copy? Lets not foget the old Xerox 660 which started it all. God they made money on that machine. Back then no one could by a copier, you had to lease it directly from Xerox. It wasn't until their patents started running out at the 17yr mark,then the Jananese entered the market and the rest is history.
My vote is the Sharp SF7200 & SF760. Great for slicing your fingers and pigs for paper feed and dumping toner. Used to take them to the landfill and spend a couple hours putting 12 gauge slugs through them on a Saturday after we got a trade in. Great stress releaser. Any other manufacturers out there that refused to break the edges on the metal during manufacture? From the machines I have worked on it's Sharp (no pun) followed by Toshiba.
As I read through these posts it seems that too many of you are not old enough to have experienced a really bad copier. Although, the Mita 513z was pretty bad. There are copier models that their manufacturers will no longer acknowledge existed.
Toshiba BD601 -- Major fire hazard. Many law suits. Before fuser rollers the machines used oven fusing. Those were the good old days.
Panasonic 2520 -- The worst copier ever devised. This machine had updates to fix the problems caused by previous update.
My first training class was Toshiba 728. At the time Toshiba recommended one full time technician for every 125 machines in population. Imagine how we afforded that compared to the digital machines today.

The only copier worse than the Mita 513Z was the Mita 513Z after the 12 point reliability fix.
I know what I know better than anyone else knows what I know.
I think the Mita 6090 was even worse than the 513z. Downtime on those pieces of junk was astronomical. You never had to worry about job security if you had many in the field. Guarenteed 1 call per week per machine.
The Ricoh 4700 (early '80s) was a single component, using a sheet master instead of a drum, fiber optic block (remember Canon NP200) and a giant cam with levers that controlled most timing functions. Prime example of fecal ingenuity.
