OKI C3200N Color LED Printer Toner Reset

Posted on by

I’ve had my C3200N printer as a workhorse for a decade until it died. Before I toss out the service manual and the instruction to reset the toner, I’ll put it here for those who still got mileage left for the printer

Here’s the service manual:
http://upload.evocdn.co.uk/olivetti/uploads/download/d-ColorMF200-240_sm_Y105560-07.pdf

Back up here:
C3200N_Service_Manual

The important pages where the service menu is in page 124-125 (Maintenance Menu), 134-136 (Menu Tree), 152 (Factory mode = Do not cut fuse of consumables)

 

Summary (https://www.fixyourownprinter.com/forums/laser/23029):

*** Do NOT use NV-RAM INITIAL RESET. It’ll screw things up (like losing MAC address). You can go into the service menu to reset toner, drum, fuser and belt individually***

Here’s the directions by user “Nono” which I think it’s the best:

A C3200N here…

I never wanted to do the NVRAM complete reset because I was scared of losing the network MAC address as mention somewhere else on this forum. And basically controlling the consumable level independently was interesting… My c3200n printer was bought last month (09/2006), guessing here that the bios may be different depending on release date (this walkthrough might not work for everyone).

Sooooo, after much button pressing, restarts and coffees.. here it is:

Get to the standard “Diagnostic mode” as describe on this thread:

1) Turn off printer.

2) Turn on printer, while holding the + and – buttons.

3) The LCD Shows “OKI User”, Scroll to “Engine Diag Mode”, press “enter”.

The display shows “Diag Mode 01.02.02 S-Mode” as mention multiple times on this thread.

At this point you should wait for the initialization cycle to complete. I mean for all the motors and gears to have finished their noises and cycles – otherwise you will end up with a LCD switching between two different info screens – not a big deal but still annoying.

Now we want to go in “regist mode” by:

1) Pressing the “Online”, “Cancel”, “Enter”, “-” and “Back” AT THE SAME TIME (not in any sequence – at the same time). Yes! That is 5 buttons.

2) After within two seconds the LCD menu will show “READY”. If it doesn’t, release button and repress buttons again.

3) The buttons release sequence is important. So, read this before letting go your five fingers: Release the “Enter” button first and THEN the four others. LCD is still showing “READY”.

4) Press the “Online” and “Cancel” button at the same time BRIEFLY. Don’t wait before pressing them after the five fingers sequence otherwise you will miss your time slot.

You can always switch back from the “READY” to the “Diag Mode 01.02.02 S-Mode” menu by pressing the five buttons again.

Don’t laugh. I know it seems a lot of gymnastic. Well I guess they didn’t want the user to find that one easily.

Now you see “Eng Diag Level 2”

Taking from someone else on this thread (with some modifications for the c3200n):

Press either the + or – button until “CONSUMABLE COUNTER SET” is displayed, press the Enter button; you are now in the menu to set various consumables.

1) Press either the + or – buttons to scroll through the various consumables, at the desired consumable (ie. “K-ID UNIT …” for the Black Image Drum Unit, “C-Toner” for cyan toner, etc.), press the Enter button and the last digit of the count will start flashing.

2) Press the Cancel button to decrease the digit amount or press the On-line button to increase the digit amount; press the + or – buttons to move along individual digits in the count. Note that it will not show the remaining but the usage (100\% means it is empty).

7) Once the count is at the level you desire, press and hold the On-line, Cancel simultaneously until the numbers stop flashing; you have reset that consumable’s count to the number you specified. Note that you may end up with a different value then the one that was entered when saving. The printer engine is probably jumping to the nearest registered/acceptable value. If someone find a way to save the exact value, let us know.

8) Press the + or – buttons to move to the next consumable and repeat at step 5.

9) Once all consumable counts have been set to desired amounts that are below their end-of-life thresholds, you can use the Back, +, & – buttons to exit through the menus (reverse of steps 2 through 4) until “INITIALIZING” is displayed. Or turn printer off and on.

10) You’re finished! Now log in to the web interface with your browser and check to see the remaining life of your consumables.

There is another way to get to the “Eng Diag Level 2” menu – I did it at one point but wasn’t able to reproduce. But this method worked for me even if you may need some practice. You can also get to level 3 and level 4 after the release of the five fingers step by pressing something else then the “online” and “cancel”.

Good luck.

termdd.sys BSOD because of remote hack attempts

Posted on by
Reply

Recently my computer keeps ‘randomly’ getting BSOD over “termdd.sys” and “IRQL_NOT_LESS_OR_EQUAL”. Upon some research on “termdd.sys”, I noticed there’s a RDP heap corruption attack (https://securitynews.sonicwall.com/xmlpost/rdp-vulnerability-cve-2019-0708/) for RDP services.

In the past, I opened up my computer’s RDP service to the wild (bad practice) by routing the traffic to the right computer. The attempts did not successfully break into my computer, but in the process, these villains are corrupting my computer memory (heap) thus causing the BSOD.

Instead, I plugged the bad practice of opening up web services that are only for me to use. Instead connect to my home network using VPN when I need to access my computers. Since then the BSOD disappeared.

Lesson learned: Your computer is not hacked by a remote exploit (probably patched enough) doesn’t mean the exploit won’t trash your computer memory till it crashes. Better use a VPN than directly opening up RDP to the wild internet.

Foobar2000 alternatives for Linux

Posted on by

I am a big fan of foobar2000 because it’s one of the most terse yet flexible package for playing music. I tried using RhythmBox that came with Linux Mint, but it’s annoying as hell. When you double click an audio file, it’ll adds to a default playlist and after it finished playing, it’ll go and play other songs you’ve previously clicked (because they were accumulated on the playlist).

Out of frustration, I tried to stick with my favorite, I found foobar2000 has a wine port available on Snap package manager. Downloaded it and realized it has a lot of work to do to make it work on linux:

  • Fonts do not scale. It’s always that tiny and not all the UI controls looks odd
  • The paths assumed windows drive letters. Sometimes if I drag and drop files from a bitlocker drive (mounted with dislocker), it’ll assume the file came from some complicated path under Z:\. WTF

Ended up downloading Clementine. It at least let me remove songs from the playlist by pressing “Del” button. But I’m not happy that it doesn’t have CDDB.

Turns out there are better options the Clementine. I found this StackExchange while searching for FreeDB options:

https://askubuntu.com/questions/541977/a-music-player-with-cd-ripping-and-cddb-lookup

Turns out DeaDBeeF (a hex pun) looks like a watered down version of foobar2000. So, Clementine, Foobar2000-Wine and RhythmBox is out.

EDIT: DeadBeef v1.82 offered on Ubuntu (Cinnamon Remix) 20.04’s repository mishandled files on an encrypted volume that’s unlocked. I went to Deadbeef’s website and downloaded DeaDBeeF 1.8.7 universal deb package amd64, installed it with dpkg -i and it worked!.

Samsung Galaxy Note 3 Charge and USB-OTG simultaneously

Posted on by

I’d like to charge my phone and use USB devices at the same time, but it seems like it requires a 64.9kOhm resistor from sensor ID pin (micro USB) to ground. Instead of melting a USB-OTG cable, I bought this adapter (schematics here)

micro USB3.0 Type B Male to USB3.0 Type A Female adapter

so that I can have direct access to the ID pin. This is a USB 3.0 give that I have a Galaxy Note 3. The same principles apply to the USB 2.0 versions for Galaxy Note 4.

According to this website, fsa9480_i2c.h has the table for the resistor ID values. Turns out 64.9kOhm is the one for both charging (slowly) and using USB devices (like mouse, network adapter, etc.).
