Section 7. Warnings

The CheckScanner settings follow the same hydra connection settings as the

master device EPSON TM series printer. Please refer to the Section 7 of

"EPSON OPOS ADK MANUAL APPLICATION DEVELOPMENT GUIDE

POSPrinter (TM Series)" for further information.

Do not set the input and output buffers below the minimum 32 bytes.

The EPSON TM series CheckScanner's EndInsertion method readies the

printer to receive a check. This setting may take a time. During this time,

all devices connected by hydra settings are frozen.

(For example, the

display marquee stops.)

During MICR mode (waiting receive a check), using the Claim method on any

hydra devices (except the CashDrawer) will return an error.

When you use CHK_DI_ROTATE_IMAGE on the DirectIO method, the size

of the same image data may be different depending on whether the rotation

setting is turned on.

During a scan operation, the state of the hydra device cannot be known

immediately. For example, as long as the scan operation is not completed,

opening the cover does not cause status to rise against any hydra device.

When the tracing mode is specified, contents of the ImageData property

cannot be written in the log file. This is because the amount of data is too

large. In this case, the message below is written in the log file.

" Data was returned normally. The contents cannot be checked here. "
