| D | Mechanical interference |
Electrical Test | The electrical test performs all of the following: | |
| D | Carriage communications test |
| D Carriage ASIC test: Values stored in the carriage ASIC registers are | |
|
| temporarily stored. All registers are tested by writing, then reading, the |
|
| numbers AA(hex) and 55(hex). When the test is complete, previously |
|
| stored values are restored. |
| D Cartridge interface ASIC test: Verifies the functionality of the cartridge | |
|
| interface ASIC. |
| D Cartridge ASIC / carriage ASIC link test | |
| D | EEROM checksum |
| D | |
| D ROM CRC test: Performs a ROM checksum and compares it to a | |
|
| checksum value previously stored. |
| D Swath RAM test: Tests the RAM used by the cartridge interface ASIC to | |
|
| store the swath. |
Input/Output Test | The input/output test performs the following: | |
D Parallel input/output test: Reads the data and status registers of the
D Serial input/output test: Verifies the ability of the
