A flashing exclamation mark is typically associated with a sever cartridge error (i.e. "refer to documentation" / "incompatible cartridges", "print cartridge(s) problem" etc.) typically indicates the internal micro-electronics of the HP #901 / 901XL cartridge are damaged. Have you tried replacing the ink cartridge with a new HP genuine cartridge to confirm?
NOTE: The cartridge's electrical wire runs at rear and lower side of the ink cartridge are very delicate and are somewhat susceptible to ink attack over time, which can lead to premature failures. In addition, the older the cartridge the higher the chance of an internal electrical failure. I suggest you first run a 'Tap 41' diagnostic test to check cartridges electrical health (this is a forced test); you may also bypass the error (temporarily) on all models which use HP 901 cartridges.
