[Misc] 4020D - Fusing Temp Adjustment

[insomniah]

Working on an issue with a 4020D that is not fusing properly onto envelopes. I am a Ricoh tech, we branch out from time to time, and this is one such branch. Familiarized myself with the prescribe commands and all.

!R! MDAT 12, 3, 0, 0, 4; EXIT;

Should this work? It didn't make a noticeable difference. I have never encountered the "Prologue/Epilogue" format, so I do not know if I am supposed to be seeing a confirmation that the script is correct or a settings change.

Also, is there a way to differentiate between trays using this? Or would I just load a parallel driver that uses a different script (or none at all)?

Have you tried to engage the "Envelope Switches" on the fuser? Make sure the paper settings are correct on the printer and in the print driver.

Re: 4020D - Fusing Temp Adjustment

Yes, the issue is still prevalent on either fuser setting. Toner is not bonding with paper, is able to be smeared easily. OEM toner and supplies - always. The envelopes are not of the highest caliber, but there is no way around that. They bought the envelopes from our company, so telling them to buy higher quality envelopes (and 20,000+ of them) is out of the question.

Re: 4020D - Fusing Temp Adjustment

Not that it will help you any, but we screwed up when we sold a bunch of FS-1370DN's for the express purpose of printing envelopes. If I had taken a glance at the Advance Users Guide I would know that you can feed up to five envelopes from the MP tray consecutively. If you send a print job of say ... 200, and the media type/size is set correctly, the printer will print the first five, then toss the rest of the print job. If you try to deceive the printer by selecting a different media type/custom size, after about 10 pages the center of the image will gradually fuse more poorly. The heat lamps and thin rollers just cannot keep up with the heat dissipation to the paper.

Our solution? We located an envelope feeding option for their old HP LJ4050. It can hold (and feed, and fuse) 100 envelopes consecutively, which was a lot less than the 2000 they had in mind, but an improvement. When used as an envelope printer the fixing film will get a toner buildup at the paper edges at envelope width ~4.25" and last ~75K prints. =^..^=

This may be OFF-TOPIC due to this being about FUSING : but, if you need lots of envelops printed...look into the specs on the Bulk Feeder PF-315 .

About the fusing ...
Do all envelopes smear; or do they start OK then after a few it starts to smear ?
Did you try different media settings through the MENU ?

From Blackcat's post (forgot how to do the bubble thingy)

"The heat lamps and thin rollers just cannot keep up with the heat dissipation to the paper."

Hi,

Some years ago we moved the thermister to the centre on FS-1000/1010 fuser as there was a fixing point (slight mod to length of wires and frame) and that seemed to work ok that i remember. not rearly the ultimate solution but a work around.

Re: 4020D - Fusing Temp Adjustment

i cant see this being a problem. my company has 15-20 of these in a dirty, cold warehouse doing up to 20k in a single 12 hour shift. All they print are labels through the cassette without adjusting the media settings and they dont smudge just create masses of paper dust and glue. a few machines are running at 1.4 million and still going strong on the original fuser unit - drums and feeds replaced. Must be some sort of work around on this.

I can see where that might help, since the center of the roller is where it starts to cool. =^..^=

You have FS4020DN's with 1.4 million prints AND they are on the original fuser unit??

Re: 4020D - Fusing Temp Adjustment

That's an impressive copy count you have there, sir. The user noticed a difference in the prints, and was happy with it. Thanks for the help!

What was the fix?

Re: 4020D - Fusing Temp Adjustment

The prologue I posted in the starting post, I didn't notice much of a difference, so maybe it was a placebo effect for the customer. Regardless, they were happy.

the fuser some how just goes and goes with the labels. the drums, dev units and reg sensor take a battering from the glue and paper dust but as a printer and what is put through it you cant knock em. the machines are 600k-1.4m and as its the christmas stock in the warehouse they now go in to overdrive. Next time im in i'll print out a status page with the meter on it - have 2 machines around the 1.2-1.4 million. considering the life of the machine is about 800-900k i think we get our moneys worth on these beasts!

That is truly impressive! I'd agree that you got your money's worth out of these...
