Just purchased a used HP LaserJet 4 Plus -- when turned on and installed it is showing 14 no EP CART -- we do not use cartridges so need to reset to default settings. Tried Power On and holding online but...


Ensure that the Toner Cartridge is installed correctly (fully
seated into the printer). Try a new Toner Cartridge. If the
problem continues, try this

14 NO EP CART Message

The printer detects the presence of the Toner Cartridge and the
level of toner present in the cartridge through the condition of the
ANTIN signal. The ANTIN signal becomes part of the serial data
stream used to communicate with the DC Controller (see Figure
7-5 for cartridge components). Troubleshoot the 14 NO EP CART
(or INSTALL TONER CARTRIDGE) message as follows:
1 Reseat the Toner Cartridge. Try a new or known good Toner
Cartridge.
2 Check the High Voltage Contacts for damage. If the contacts
are dirty or damaged, clean the contacts after the repair.
3 Replace the High Voltage Power Supply.
4 Check and reseat the HVPS cable.
5 Replace the DC Controller.

After installing a new toner cartridge in my HP Laserjet 4Plus, I have an error code 14 no toner cart and cannot print.


1. Reseat the cartridge. Try a new or know good cartridge. If OK, stop.

2. Check the Hi Volt contacts on the cartridge for damage. If the contacts are dirty or damaged, clean the contacts after the repair.(This is especially important if the cartridge is recycled.) If OK, stop.

Before going further, evaluate the cost effectiveness.

3. Replace the Hi Volt Power Supply. If OK, stop.

4. Check and reseat the HVPS cable

5. Replace th DC controler

At times i get a message 14 no toner cart and then i am unable to make prints


No Toner then it prints again..
This could be lower toner, a generic toner cartridge will sometimes produce this, or dirty contacts where the cartridge lays in machine.
Look at the toner cartridge, where you see shiny silver or bronze, clean excess toner off, also in machine where toner cartridge lays, clean all excess toner out.

My printer keeps printing black smudge like lines on the sides of the paper. Can you tell me what this might be?


usually its a defective toner cart. recycled carts are just refilled, they are not reconditioned. I would remove that cart, clean the mechanism, and replace with a new cart.
