[Misc] C450i slowed printing speed whilst combined with a FS533

[C-Dawn]

Hi.

I have a C450i of which a customer complained was printing slower than the old one which was a C454e. I assumed this was just imagination but when i got there and timed the print speed - 45 pages in 1 minute i saw that it was actually hitting 35 pages a minute.

I tried updating the firmware but to no avail. After i tried disconnecting the FS533 and guess what? It goes back to 45 pages a minute.

I then proceeded to mount a brand new FS533 to the same machine but the speed goes back down to 35 pages per minute.

Does anyone have a clue as to what can cause this?

I tried the same test on a new machine that we have in the office and it can print 45 pages with the FS533 mounted.

This machine is not very old. Only gone 10k so far.

What about copying? Place original on glass and copy 50 pages and see what cpm speed is? Remember to start timing after first page out. There is around 6-8 sec delay for first page when copying so don't count that.

If speed is slower with just printing maybe a different driver?

Did you do firmware with the FS533 attached?

Silly question. Both cases in LEF orientation?


That FS533 POS comes a long way now. So may used units that gets thrown of x-lease machines making me wonder if that one was supplied new.

Maybe there is some setting for priority of quality instead of productivity(speed).

I've tried copying in the usual copy screen and using the test mode in service mode. I've also accounted for the delay before the print.

I have now tried updating the firmware of both the machine and the FS533.

I tried data clear in service mode and set it up again without any change in cpm.

Testing between trays does nothing either.

Copy speed is generally based on the engine ONLY, from paper feed to the exit area, using A4/LT page sizes. These speeds do not take into account the machine options. If a page has to go through a bridge unit and finisher, it takes more time to get to the exit. The finisher also has to move the stapler out of the way, dampers, exit trays get aligned and prepped, etc. This could easily knock off 10 pages a minute.

Then the question did the C454 have a FS-533 on?

CPM speed is based on using 1st paper tray. If you tried on a new machine at office it has to be a setting on something weird exclusive to that machine, connection, etc.
If it was 1 or 2 ppm difference then it would be no big deal but 10 ppm min is substantial! Customer might as well bought a C360i and saved a lot of $$$.

My gut feeling is it has something to do with that FS-533 slowing machine down....

But he mounted a brand new FS-533 and the result was the same.

I remember a technical information about reducing the output speed if a finisher is mounted on 45/m devices. (Paperjam)
Unfortunately I can't find it anywhere and I don't remember if it was for the 450i or 458.

The previous C454 had a FS534sd mounted.

Regardless new or not I still think it has something to do with the "FS-533". I would be willing to bet if it had FS-539 or FS-540 attached it would be 45 ppm or very close.

Not sure if you tried timing when copying off glass in B+W mode? What about without the FS-533 attached?

Also ppm timing has to start after first page out which is C450i: Color: 5.0 sec. or less
B & W: 3.8 sec. or less.

In previous post I had mentioned first page out was 6-8 sec which is for older models.

Very easy to find out. disconnect the finisher and time it.

The FS-533 has 3 different items numbers based on the engine. Is it possible a wrong item number will function but slow it down? With all the supply chain issues, they might have sent whatever was left on the shelf. It's a long shot but figured I'd mention it.
