Those mainly are leased on an understanding that the business will do an agreed maximum volume of colour/mono printing. For that, they get the toner cartridges supplied free. It's a tantalising offer for some business.
All comes unstuck when the staff learn of this 'free' toner supply, and they start printing colour like the cartridges will be supplied like this for ever. Er, nope.
A common branch support job for me has been running about setting passworded access to colour printing, and just restricting this to senior managers. There are a number of methods, either local passwords or integration with the windows domain.
For that I need to get into the maintenance section of the printer, and then there is a master password :( Sometimes Ricoh installers will change this from the (easy) default :
- to make my life difficult 2. to reduce support calls from IT user misconfiguration, 3. to encourage chargeable call-outs calls (to enter their password), or 4. to lead users and 'fine them' for exceeding their agreed colour use.
Paper feed problems are the worst with some lower end business MFPs, especially when staff attempt to recycle old "printed one side" paper. Then the things get thumped and the trays even more damaged. They have a hard life :(
