Sharp JX-9460 ...what ARE the reset secrets?

[Henry]

Folks:

I've got a JX-9460 that printed perfectly right down to the last drip of
toner. LCD message: "REPL. TONER".

OK, got refilled toner (JX96ND) and drum replacements (JX96DR) --per
recommendation that drum is replaced for every two toner cartridges.
Installed. Still get "REPL. TONER".

<Long, depressing story of quest for technical information omitted.>

As far as I can tell, I'm supposed to set the counters as follows:

DEV 00000
DRM 00000
DEVTM 0000
DRMTM 00000
LIFE 000
TNL 100

and I can defeat the crazy fuse mechanism by going into diagnostic mode and
pressing the up-arrow and down-arrow keys simultaneously.

No button combination I tried --and I tried a lot of them besides up+down --
brings up a "FUSE FLAG RESET" message. I can't find anything that looks
like a fuse on either cartridge. (There's no tape hiding anything that I
can see.) Is there really a fuse or not?

With the settings listed above I get the printer to go through a whole lot
of stuff: It puts up "READY [LJ3]" on the screen, this message starts
flashing, a distinct noise occurs for a few seconds, and _then_ I see
"REPL. TONER" as usual. Depressing.

One posting somewhere says the "DV" parameter must be set to a positive
number or the printer won't work. Apparently, this is not the same as the
"DEV" value because the printer works better (but still fails) with DEV
nonzero (I set it to the maximum, 30000).

Someone posted a message: "The remanufacturer probably didn't refill the
developer on the toner cartridge." Huh? Would it make sense to refill one
consumable and not the other? Are there really two consumables in the
JX96ND toner cartridge?

This is not even my printer -- it belongs to my elderly neighbor, who is
growing increasingly distraught over this trouble.

Can anyone provide definitive help, please?

Thanks,

Henry

This is for a TI microLaser Pro, which uses a Sharp JX engine. I
don't know how close this matches your model.

Turn the printer power off.
Press and hold UP and SELECT- turn on the printer power.
The display shows PCU DIAG MODE x- release the keys.
Press SELECT until the display shows TEST PRINT.
Press FORM FEED- the display will show P=xx H=xxx T=xxx.
- These are the levels for the Printer, Heater, and Toner.
- After several seconds to a minute the printer will pull a piece of
paper from the upper tray and print a page with lines.
- During the actual printing process (when the paper is being pulled
from the tray) record the T count: __________.
If the test page does not print, press RESET- the display shows TEST
PRINT. Perform the test print again.
The nominal T count is from 85 to 105. A T count that is markedly
outside this range may indicate a toner mixing problem that requires
service.
Any T count lower than 24 or higher than 143 requires service.
If the display shows REPL TONER, the Image Cartridge is used or
defective, or the printer requires service.
Press SELECT until the display shows COUNTER SET.
Press UP- the display shows DEV xxxxx.
Press SELECT until the display shows TNL xxx.
- The TNL count should closely match the T count recorded during the
Test Print (+/- 5)
- To change the count press PREVIOUS to lower the number and NEXT to
raise the number. The limits are 24 to 143.
Change the TNL count to match the recorded T count.
After changing the count press SELECT, then UP- the display shows
COUNTER SET.
Insert a sheet of paper in the manual feed slot.
Press FORM FEED- the printer will beep (the paper does not feed).
Remove the paper.- the count is now saved.
Press SELECT until the display shows TEST PRINT.
Ensure that there is paper in the upper tray.
Press FORM FEED- the display shows P=xx H=xxx T=xxx. The numbers will
be moving up and down during the test print.
- During the actual printing process (when the paper is being pulled
from the tray) record the T count: __________.
If the test page does not print, press RESET- the display shows TEST
PRINT. Perform the test print again.
Ensure the T count closely matches the set TNL count.
After several seconds to a minute the printer will print a page of
lines- the display will show TEST PRINT.
Turn the printer power off, then on.

Thanks for your response to my post:

I think it is identical, except that the buttons are labeled a bit
differently. I can adjust!

Turn the printer power off.
Press and hold UP and SELECT- turn on the printer power.
The display shows PCU DIAG MODE x- release the keys.
Press SELECT until the display shows TEST PRINT.
Press FORM FEED- the display will show P=xx H=xxx T=xxx.\

Ensure the T count closely matches the set TNL count.
After several seconds to a minute the printer will print a page of
lines- the display will show TEST PRINT.
Turn the printer power off, then on.

<what a friggin' mess>

Wow, that IS a friggin' mess. It's way past my neighbor's bedtime right
now, or I'd run over and try it. Tomorrow!

In the meantime, could you give me some reassurance about the %*$%@#$*@%#%
fuses. I didn't find any fuses -- I'm a computer engineer so I've got a
pretty good idea what would would look like. So are there any fuses? Does
this engine have a "fuse reset"?

And what about all the other counter values? What values do they need to be?

Thanks,

Henry
