Ink jet recording apparatus
First Claim
1. An ink jet recording apparatus comprising:
- an ink jet recording head for receiving supply of ink from an ink cartridge provided with storage means storing data for determining compatibility of a recording apparatus; and
control means for determining compatibility of ink based on the data in the storage means and executing print operation, wherein said control means determines;
if compatibility to an ink cartridge cannot be confirmed when the ink cartridge is mounted, the recording apparatus generates a caution and awaits input of one of a continuation instruction and a cartridge replacement instruction by a user before the recording apparatus executes a subsequent print operation, andif the recording apparatus executes the subsequent print operation upon input of the continuation instruction by the user, the recording apparatus generates the caution again after a predetermined amount is printed.

Abstract
In an ink jet recording apparatus comprising an ink jet recording head 3 for receiving supply of ink from an ink cartridge 4 provided with a storage device 7 storing data for determining compatibility to a recording apparatus, and a print controller 10 for determining compatibility of ink based on the data in the storage device 7 and executing the print operation, when an ink cartridge 4 is mounted, if compatibility to the ink cartridge 4 cannot be confirmed, a caution is given and the recording apparatus awaits an input of a continuation instruction by a user to execute a subsequent operation. Even if a cartridge whose compatibility cannot be confirmed is mounted, printing is enabled as much as possible without incurring damage to the recording apparatus.
