Thanks everyone for everything! I will try to install the screw in the fuser, hope this will help.
Thank you for the picture!Originally Posted by femaster
It should be obvious, but I'll say it anyway ... make sure you do the same to both sides to keep the pressure even.

From the original post.. You said problem is only when first used. So maybe one or both of the lamps have leaked out some of the halogen gas and are weak, but still have continuity, so they are slow to heat on first use. Watch for multiple C3421, C3423 codes in service history... Cold lamps from startup. After the press roller gets fully hot, it will work ok until it goes to energy save or the next morning. I have a couple of customers that occasionally have cold offset in the morning. I blame the lamps. If they don't want to buy another fuser, I tell them just open & close the door after warmup, or run 2-3 blanks first. They're fine all day then unless it's really cold and it goes completely room temp. Swap the fuser to test.
Can't be aftermarket toner bc you changed DV. The initial toner is OEM for at least the first 20-50 pages or so... if you used OEM DV. We always use OEM DV.
We love the rollers our good friend from Germany has. They outlast the OEM at least 2-3 times as long. The roller or coating must be a bit thicker, bc we increase temp +5, sometimes +10 degrees due to cold offset. 90% of all our 3 series are running his UFR for years now, with some with oem but 90% use aftermarket toner.
We re-use the oem press rollers at least 2 rebuilds.
Almost started splicing bh200/250/350 lamps as mentioned, but for now enough are being traded in
We made friends with a KMBS dealer tech who was pitching used fusers whenever the UFR is worn! KMBS promotes recycling...

feel sorry for you guys - we just put brand new fusers in. By the time you have dismantled them and rebuilt, then sorted out the various issues ....
Nice when you or your boss can afford it, but being an Indy having to compete with the fat cats thru prices I prefer to rebuild them. We use those "German UFR's", recoat the thermistors with teflon tape and let the fuser unit have another life. Some machines we do this 3 times. Our 230VAC lamps rarely fail btw.
