Question about Minolta magicolor 2300W Laser Printer

4 Answers

Identifies itself as NaltecN1, which is a controller chip inside the Minolta Magicolor 2300W

The Magicolor 2300W was already installed, but it has been rarely used. It has barely done 1500 copies in its life. This problem originally occured intermittently, and fixed itself after rebooting th eprinter, but not today, after several reboots.
When the printer is turned on it claims to be a NaltecN1 and wants to be reinstalled. The correct driver for this printer will not satisfy this misidentified printer and the Status Monitor misidentifies the printer, and refuses to work with it, so that I can't use the Status Monitor to at least remove the toner cartridges to give them a shake, because, although the Color Toner low light is on, and it won't print, I know that there is at least 95% toner in there, from the previous time that the Status Monitor actually worked. (This has been a very annoying printer throughout its life, being entirely dependent on Windows and the Status Monitor, so that I can't print to it from any of my Macs, only from the Windows machines.)
I have tried this with parallel and with USB on a desktop and a laptop running Windows XP SP2.

    I have the same problem. My printer doesn't works on three PCs.

    One day before, it works well, but today it is a NALTECN1 and want's to install a driver.

    A week beform, i have the same error, but i made a restore of windows an it works again. I think, there is a defect on the printer.

    Make the firmware-update, and the printer works again. Use a parallel-port-cable and don't forget to change LPT1 to FILE before updating the firmware and change back after done.Then switch the Minolta off and on, and it works agian.

This is a known problem of the Flash EEPROM on the controller board losing data. The EEPROM is an Atmel DataFlash AT45DB021B type.

If you can still get the printer to boot (like you indicated that it was occasionnally possible at one time), do a firmware upgrade immediately. This will erase the EEPROM and write it again, thereby writing fresh charge into the storage cells and allowing them to hold the data for some time again.

If the printer won't ever boot properly, you'll have to remove the EEPROM (desolder it from the controller board), get a replacement, program the replacement with an EEPROM programmer, and put (solder) the replacement back in. You can also rewrite the original EEPROM with an EEPROM programmer, then it will work for a while again, though it's not known for how long exactly (sooner or later one of its storage cells will deplete again).

For programming the EEPROM (new replacement or original part rewrite) you will also need the firmware binary file.

Konica Minolta does not provide one in the correct internal EEPROM format, but you can download an archive called "MR1_3.zip" from their website, and this will contain a firmware file "mr-3926.nal" with a size of 128 kB. It will be missing some padding data so you can't write it directly into the EEPROM, but it can be converted. The conversion can (in theory) be done in a hex editor, but it would be a long and tiring process, so better write a small program to do it. Here is the algorithm:

1. Read from the source file one full 256-Byte block at a time.
2. If this is a complete block then skip steps 3, 4.
3. If this is the last block (it is smaller, not full 256-Byte size)
4. => then fill it up with 0xFF bytes to full 256-Byte size
5. Copy the (now full) block into the destination file
6. Write additional 8 Bytes after each block to the destination,
7. => the data to write is hex: "FE, A6, 7E, 0D, AD, 73, F8, 26"
8. Goto step 1, process the next block from the source file.

When all is finished, the resulting (destination) file will be 132 kB (135168 Bytes) in size total. This file can now be written directly into the EEPROM with an EEPROM programmer. When you put the newly written EEPROM back in, the 2300W should work. At least mine did.

    Obviously this was meant for people with the same problem doing a google search (the site comes up on top). The original poster will of course have junked his printer a long time ago by now.

I finally was able to talk to a Minolta repair person and here is what they said: The Naltec message is an indication that the
controller printer's controller board has failed. I asked for a price quote on the part and was told it is either $160 or $560 for the part. Since I needed toner cartridges, it was much cheaper to buy a new printer.

A firmwareupdate is not possible, because the correct driver is not able to be installed, and so you can't connect the printer.
I have the Problem the color toner led is always on. I have every toner cartridge opened an reset the switch for toner emty, but it doesn't work
