8518a "Adjusting. Wait until printing resumed"

Re: 8518a "Adjusting. Wait until printing resumed"

Well at least you have the 1600 firmware, which HOPEFULLY will help with the C471 issues. That, has been a NIGHTMARE.
We don't have the issues with the 55,65CPM machines. We told Toshiba over 18 months ago the operating temperature
of the 85CPM machines was too close to the blow point of the fuse, but, we're techs, what do we know.
We all laughed when the 1600 was released because they said that the temperature was too close to the blow point of the
fuse (we had already dropped 3-4 temperature settings about 6 months ago, which CUT our 471 issues by a lot!)

When you replaced and reset everything, after the developer calibration, did you also do the IQC? 05-2742
Then there are two other ICQ settings for 600/1200 DPI.
I find it easier, than looking up the codes, to just go back and set 08-9022 to 3, power cycle and it pops into
"easy setup" to the point it is ready to do all of the gamma ajustments.

This sounds like a developer density issue to me, not a fusing issue. What service modes did you run at the PM? Knockoff toner? =^..^=

I sent a slack message to my techs Monday when I saw the eastern regiional conference calls posted on FYI about that door switch.
I've told them if they get more than one 471 after the codes are changed, with a rebuilt fuser, to change that door switch since it is
easy to get to. Plus, I want the old switch back so I can cut it apart to look at it.
My guess is that as you know, customers will just push on the front edge of the ADU to close the door, and I'll guess that the back side
isn't latching all the way, causing the switch to arc.

Re: 8518a "Adjusting. Wait until printing resumed"

I'm thinking to try printing some heavy media to see if there is a difference between with the adjusting?

Check if the toner hooper assy is mounted correctly in those clips and the blue plastic arm inserted into the developer discharge port - the one wrapped with the ATS harness. Any other errors in error history?

Thanks for the replies,

I spoke with Toshiba Tech support, they said they have a very small case file on this issue, but said there were 2 similar sounding issues. They told me the first was solved by running adjustment mode, 05-2734, which I'm not sure I understand because when it did it returned a number, 88, but no way to adjust it, the same with 05-2737, which returned the number 32, 05-2740, which appears to not even exist, and then 2742. Those did not correct the issue.

The next thing they told me was that there was a chance the Hdd had been corrupted, and to try to format the hard drive, and then reload the firmware, which is where I am now, I formatted the hard drive, reloaded the firmware, they warned me that it is possible that if I created a clone file it was possible the corruption could be copied onto the clone file and reloading it might return the issue. So after reloading the firmware with the help of their IT, we restored the settings manually. I left the call open for parts like the transfer roller, and tbu kit to give me the opportunity to return and check on the machines performance. After formatting the hdd, I waited for print jobs to enter the queue, but only 2 jobs arrived, one was 160 pages duplexed, and the second one was just like 20 pages. It performed those jobs without going into the "adjustment" message. So 3 hours later, I left telling them I would return with parts.

Tech support also mentioned the possibility of an IH board, but I am having a problem buying that one because it wasn't an issue before replacing the parts I previously replaced. They also mentioned a performance index, and a details threshold, but I had other calls I needed to get to, and decided any further time spent there today would be frivolous.

They also mentioned TSB 1902, and 1903

I will return sometime tomorrow to see if there was any improvement.

Thanks again for the replies

I think TABS default position is to point to the fuser/IH board, TSB's that have to do with the fuser.

It's a shame too. The fuser in the old 5520's were an issue, but when the 5540's & 5560's came along, those fusers
would sometimes go a million copies before failure. So....LOL let's change the fuser when the 5508A series came along.
I remember when I went to one of the first EBN schools in Chicago. They had the 08A at some trade show and rolled
it in so we could see it. We were worried because when they said they were going to replace the 555/556/557 series
with a new b&w, we thought we'd have to figure out the bugs until they got them all solved with a completely brand new
model.
They rolled it in, and I think I jinked it for everyone. I said wow! They took a 5560, took the color out and made it a b&w
machine (here's the kicker) WE WON'T HAVE ANY PROBLEMS WITH THIS MACHINE.
I just had to tempt "murphy". And, on the 08 & 18 series he's been kicking our butts ever since.
We are just starting to get a handle on the C471's by using the Shin-Etsu oil, doubling the amount, lowering the temperatures.
Also by keeping the power saver/super saver engaged along with auto power off after 240 minutes. We have a ton of these
in schools and before, if the schools were out for an extended vacation, covid or what not, we'd get a bunch of ripped up belts
on the first day back because all of the oil evaporated out.

Back on topic (sorry for the rant...C471's just tick me off to no end) I didn't see, but have you done the HDD file/partition check
to see if something is whacky doodle?

Re: 8518a "Adjusting. Wait until printing resumed"

Glad you mentioned that, because, running off my rusty memory, I did a low format on the hard drive, and I thought, I think I need to format the partitions before installing the firmware. So I selected format partitions, and just about everything but the bottom 3 said error. admittedly need more experience with hard drives, but after I got that, I reinstalled the firmware and dealt with the IT on setting the machine back to proper settings. Wasn't able to make it there today, but I did just message my parts support and asked them to order me a hdd.

Re: 8518a "Adjusting. Wait until printing resumed"

Afraid to mention this machine, but I did find the drum thermistor was misformed, and that seemed to solve the problem. Have not been back to the machine for over a week. (knocking on wood).

Nice catch
