IMC 4500 Fusing issues

Re: IMC 4500 Fusing issues

Hello everybody

I have the same problem on 4 or 5 new IMC 4500. There are reports on the prints (as if the fuse dont heating enough).
We have already update all copiers, change fusing unit with a new, increase fusing temperature... always the same problem !
We have called too the Hotline but no solution for now... other similar cases are know today.

Have you an idea how I can resolve this problem ?

Thanks you

try to change driver setting, on "preference setting>type of job" select from "velocity" to "quality" and look what happen

Re: IMC 4500 Fusing issues

Have you tried what your colleague Luca tells you?
Is the toner original?
Have you tried different paper than the one the client has? If possible one that is not the client's own in case he has a poor quality consignment.

There must be a common factor between the machines for a batch of new machines to be generating the same problem.

We may have a lead... we ask again to the hotline and they answer there is a line in the SMC report which say the toner type. We take OEM toner but not at Ricoh directly...
So, on the IMC 4500, we use this toner and the bit on the line is different if the toner come from ricoh directly or our provider... We think the toner from our provider is toner for US or another country but not for France... We test with toner from ricoh actually but the dev must turn in order to evacuate the old toner... Maybe is that

I always solved this way 95% of the time (driver setting in quality mode at max change also paper weight) ... the other 5% was the thermistor to be cleaned/replaced

If the toner only says OEM and not Genuine Ricoh it is an after market knockoff. It will have the same main ingredients but they are not guaranteed to be of the same quality. They might even manufacture for Ricoh but if they do it is probably from a batch that Ricoh rejected.

There is information available for the toner Cartridges using different toner chips for different regions (EU/ASIA/NA).However,I am not sure if the genuine Ricoh toner will be an issue after the toner cartridge has been accepted by the device when it was replaced.From what I can understand from your information is that you are not sure if the toner you are using is a genuine one or not, and that could be the reason for poor fusing, right?
Thanks.

it's genuine toner but not for France... maybe is that

Hello Everybody,

I again have the problem on one of them. It appears sometime, not all the time, just on the 2-3 first pages... the fusing unit is just changed / fusing temperatures are increases / firmwares update ok / I have no more ideas

You can try and bump all standby-related temps for the upper/lower fuser roller (1-107-001 onwards).
If you bump the target temps while using plain paper just bump ALL "plain" related SPs.

Also make shure the toner density is not too high.

Thank you for your request, I already bump all standby-related temps for the upper/lower fuser roller

Re: IMC 4500 Fusing issues

OK, perhaps you need to go a little further. Can you tell a little about the enviroment of that machine? Room temp/humidity, AC or an exit door to the outside nearby?

In the past I had an issue like that and that customer had 2 IMC of the same type - one was placed in a medical lab and the other in an office. Lab one did cold offset every now and then during first B&W copies/prints even with modified settins, different fuser - office one was working fine. Finally I swapped both machines among ech other and guess what, the lab machine was working fine in the office and the office machine did the same issue in the lab enviroment.

We never finished that story since the customer was ok to set the lab one to color mode. Funny thing is that when I was there with my tech, I didn't really felt an issue in the lab enviroment but at a later visit one of the female workers was in a chatty mood and told me that "sometimes they can only endure this place wearing jackets" since it can become very cold.

I was thinking about getting a temp/humidity logging device (something like this Klimadatenlogger BL30 | TROTEC) for future cases but didn't make a purchase yet.

Many years ago I had an Aficio 1055 in a trailer office at Tehachapi State Prison where over night lows could drop below freezing. They had to wait until the room temperature had risen to above 65 for at least 30 minutes before turning the 1055 on or it would throw throw warm up errors.

For less extreme environments maybe tray heaters might help.

LOL servicing an A1055 in a trailer must have been fun

Tray heater is probably a good idea, haven't ordered one in years but there weren't pricey back then.

Hello, the office temperature is ok... no humidity... it will be weird that appear on several copiers not at the same place...
