T 2.20 Inadequate or incorrect supply of consumables

Many devices used every day in offices such as fax machines, printers, data backup drives etc. require a sufficient supply of consumables for smooth and uninterrupted operation. A lack of consumables may cause critical interruptions to operations. In emergency situations, it may severely limit the ability to take action, resulting in high consequential expense.

Examples:

• Incoming fax transmissions cannot be printed even when received correctly if the supply of paper or ink is exhausted. Due to its limited capacity, the buffer memory can only delay the rejection or loss of fax transmissions, but cannot prevent this completely in the long term.
• A new tape drive is purchased that is not compatible with the old tapes. No new tapes for the new drive have been purchased, with the result that data backups cannot be performed for several days.
• An important print job is pending. However, the spare ink cartridge purchased is not designed for the printer.
