Reset consumable Epson Aculaser AL-C2000 (C1000) Transfer Belt Photoconductor Fuser Toner USB to parallel


If you use a 'very old' but still very functional laser printer, like my Epson C2000, you'll occasionally be irked (by the printer) to replace one of its expensive consumables. This note explains how to delay the replacement to the future, perhaps when the print quality has deteriorated. If your thinking is like my thinking you probably

a) aren't too bothered by print quality because you only use the printer for xyz.
b) you have another good printer for best printing anyway
c) aren't too bothered if you damage it, i.e. you damage it
d) feel it's urgent and you don't have a replacement consumable just now

Normally the printer will warn you well ahead of time that one of the consumables needs replacing. Sometimes the printer will even refuse to print until you replace one of the consumables. There are three approaches to this

1) Replace the toner / fuser / photoconductor / transfer belt / whatever

2) Buy a reset fuse for a few £ or $ - it's something like a 100mA, 250v fuse 

3) Short the fuse connectors - this is free, explained as follows

What to do 

If you chose 3) above here's what to do.

Remove the consumable from the machine. Inspect it from every angle for a pair of metal strips behind which is a fuse. Ping these metal contacts off, remove the fuse but then replace the fuse wrapped in kitchen foil. Replace the metal contacts and place the consumable back in the printer.
(There may be more than one pair so so find the correct pair to ping off).

When you start the printer the controller will register the old consumable as a new one and reset its counter. You can print a Status sheet to see if that's happened if you like, but the last thing to do is to undo what you just did, removing the aluminium foil.

Warning

This is not a good thing to do if the part that that needs replacing eventually breaks up inside your machine. That's me imagining the worst. But as I listed above I don't care too much about this printer.

USB to parallel adaptor - by the way

The network interface on my C2000N seems to have failed so I was stuck trying to find a way to print using the parallel interface. I bought a Sabrent USB to parallel adaptor which works well on a modern (2018) computer without any additional software. Prior to this I acquired a USB to parallel adaptor but this was some old cheap thing that required old drivers which failed to work well for me.

Using CUPS as printer server on a Raspberry Pi - HP 1018 and Epson AL-C2000

This is one of best and most overdue project I've ever done - it allows everyone to print without the need for a cable connection and without setting up printer drivers. I can at last print from every computer, phone or tablet Android or IOS.

The problem with printers, and many peripherals, is that I change the computer so many times in their lifetime I feel than I am forever installing drivers and problem solving with them. After twenty years of this it was time to get a printer server.


UPDATE - in 2020 I moved to a CUPS Docker based server to replace this setup although it was working well. I'll write up the long story in time. In short we install Raspberry PI OS Lite > then OpenMediaVault 5 > then Docker & Portainer > then CUPS with Foomatic drivers.

Solutions to problem printers

HP Laserjet 1018 on CUPS / Linux printing on Raspberry Pi

This very popular, reliable and cheap to run printer is different. It needs a proper driver with software support from every computer I've ever used it with. If you look at the list of printers supported by HP you'll see the HP 1018 needs a plug-in. So do as follows:

Instructions to install CUPS and HPLIP hp-linux-imaging-and-printing. This adds the printer to the list in CUPS. The cups in line 3 below is redundant if you followed the Howtogeek setup above.
  • sudo su
  • apt-get update
  • apt-get install hplip cups
  • usermod -a -G lpadmin pi

Instructions to install HPLIP plug-in

You might as I get an error from the following. However the error text helpfully tells you to try 'interactive mode' where you answer questions to install the plugin. 
  • hp-setup OR
  • hp-plugin

Instructions to set up CUPS with the HP 1018

Add a new printer. The printer needs to be on. Click the box to make the printer shareable. The HP 1018 should be in the list of printers with a note 'requires proprietary plugin'. Ignore this as you've installed that. 
Finally you'll see the printer as e.g. hp:/usb/HP_LaserJet_1018?serial=KP0GHC8

Epson AL-C2000 on CUPS / Linux printing on Raspberry Pi

This printer is less different however I've too often found it fails to print as reliably (eg mono instead or colour; portrait printed as landscape) using the standard CUPS gutenprint / foomatic drivers whether I chose PCL5 or PS3. I tried Generic Postscript too. 
Instead of choosing from the list of printers in CUPS, I used the PPD that came with the printer and that did it. 

My PPD for Epson AL-C2000 (stored on Google Drive)

Adding the printers to your Android phone or Mac.

The printers installed on CUPS should be discoverable when you choose Add Printer .... On my Mac the printers appear as Bonjour devices. Click the + in Mac Preferences / Printers. Choose from the list of Bonjour devices. Printers can also be installed on Android using the default Printing Service (you must disable Cloud Prin on the phone). IF the Mac complains that the driver comes from a different manufacturer etc, you'll probably also now need to add the PPD or add the drivers to this local machine. 

Adding the printers to your PC

Windows 10 didn't discover the printers too easily. I opened up CUPS and navigated to the printer page and copied the URL (http://192.168.1.xx:631/printers/EPSON_AL-C2000). Give this URL to Windows after it fails to find a printer.

You might want to rename your printer
Try this http://jennyandlih.com/renaming-printer which enables you to edit the config file. 

/etc/init.d/cupsys stop

sudo nano /etc/cups/printers.conf
/etc/init.d/cupsys restart




Replace battery & volume control on Oneplus One OPO

How long did the battery last? In 2018 a Oneplus One battery was three years old and not quite making it through the day. I replaced it successfully but damaged the volume control in the process. This note tells how it finally worked out well. 

Extra tips to replace the OnePlus One battery (£12)

Batteries that look genuine could be found for around £12. You have no idea what you're buying and no idea if the reviews are fair.

I add these tips to instructions found on Youtube, to replace the battery on the Oneplus One:

a) The back cover of the case does come off and you will damage it use you use a screwdriver. Use a wide flat tool because the leverage on a screwdriver tip is too focused. All that's left to do is unscrew the plastic panel holding the battery cable, and then prise the battery which is glued with tape to the phone.

b) The instructions did not remind me to take care with the ribbon cable of the volume control. I caught the ribbon and squashed it badly. For a while therefore the volume was adjusted using the on-screen volume control.

Replace the OnePlus One volume control (£4)

A volume control switch and ribbon cable cost me just £4. Again Youtube instructions show how to solder off the old volume control and solder on a new one. It requires skill so maybe get help from a regular solder-type person as luck is not guaranteed.
