Versatile paper handling to be quite a period of 35 ppm. It is the only 11x17-inch monochrome desktop laser printer in the product line, and the first new 11x17-inch desktop model introduced by Ricoh since 2005.

Ricoh SP3410DN Toner, Ricoh Aficio SP3410DN Toner Cartridges.ġ3-11-2018 Choose full driver and software package because it can indicated what the main problem of your printer. The site is working after I made the migration changes, all in /config/ Now RICOH AFICIO SP 3400DN DRIVER Turns out nobody warned us about that for NextCloud! That config file also contain database settings, so I bet if I change the database names or database usernames, I’ll have to come back and edit it manually too. I recalled a when I rename WordPress databases, I have to manually edit the changes in wp-config.php.
#RICOH SP C250DN TONER RESET HACK PASSWORD#
Bingo! Īnd to my horror the SQL password is stored in plain text in config.php! WTF! I’ll choose a password that’s dedicated to one use and not shared! So I searched for config.php and found it’s located in /config/config.php.
#RICOH SP C250DN TONER RESET HACK CODE#
Line 99 of console.php didn’t give too much hint so I looked at the code around for some sort of config-related operations before. This means some programmer got lazy and hard-coded the path somewhere! I also noticed the old path was regenerated with just a /data folder with two files # "address" counter sync up with the hex code index in file Target_device="/sys/class/leds/led0/brightness"Įcho "Detected toner chip for color: $color"Įcho "Short flashes before starting. Strip the 50: header, discard all "-" entries, and you are left with the detected address # Keep the 0x5* address lines since only 0x50~0x53 is valid. # This line is disabled because it takes too long to unregister i2c_bcm2835 to start from a clean slateĬOLORS=( ="yellow" ="magenta" ="cyan" ="black" ) # Be sure i2c is enabled and installed (it's turned off by default) on Raspbian # The pad closest to the edge is GND (-> Pin 9), followed by VCC (-> Pin 1), DATA (-> Pin 3), and Clock (-> Pin 5). # The chip data is in file named "black" "cyan" "magenta" and "yellow". # This program detects rewrite the toner chips to "full" for a Ricoh SP C250SF/DN Printer using Raspberry PI (defaults to BCM2835 models such as Raspberry PI Zero Ｗ） I’ve designed the program that it’ll detect the chip if you hook it up right and immediately program the chip (takes only a second), so you don’t have to hold the jumper for too long to worry about unstable contacts. Other cases (you are likely going to run into) are pretty much data lines getting hooked high or low levels while power lines not getting any supplies. So no worries if you didn’t touch the pins right! The only case it might go wrong is if you intentionally flip the block and slide it by two pins (reversing Vcc and Ground). Brilliant! The worst case for my poorly aligned jumper block is that SDA and Vcc might touch each other, but it doesn’t matter because it’s a perfectly legal hookup (just not communicating)! When reversed, SCL is set to low (Ground), SDA is pulled up to Vcc while there is no power supply, so no damage is done. My guess is that it’s a good design to put the Vcc next to Ground on one side instead of making it symmetric so the polarity can be reversed. You might be worried about shorting into the next pin or hooking something up in reverse damaging the chips, but luckily the chips survived. See pictures here: Can press the pins down by using jumpers Since I don’t have cheap pogo pins lying around, I took the 2.4mm pitch (the standard size used in PC, Arduino and Raspberry Pi) jumper block I have (so all pins are set at equal lengths to make simultaneous contact) and hope somehow there’s 4 pins that kind of align with the contact, and it did. Please remind me in the comments section if you find out who should I credit it to. Sudo i2cdetect -y 1 Sorry I forgot where I got this image from.
#RICOH SP C250DN TONER RESET HACK INSTALL#
While looking for the pinouts ( ), I discovered a useful tool called i2cdetect that allows me to find out the address of the chips which means I can write a program automatically figure out the right image to load to the chip without looking: sudo apt-get install i2c-tools The electrical pins we need is clustered on to top left, Pins 1 (3.3V), 3 (I2C SDATA), 5 (I2C SCLK), 9 (Ground) I am using a Raspberry Pi Zero W so the chip is BCM2835 instead and I can use 100Kbps/400KBps instead of 9600 baud as in the original code This is based on the Raspberry Pi implementation of the Toner chip reset:
