Imaging(error)
When an error is detected in TIFF or JPEG image except PDF while the direct print function
works, it conducts error processing.
Following errors are detected during direct print processing.
• Initialization error
• Work Memory full
• Invalid data
• Processing error
Initialization error
This error occurs when specified memory cannot be allocated at the startup of direct print
function. When initialization error is detected, the function prints pages that have already
been rendered and executes the following processing.
• Regardless of [Warning display] setting in IMAGING set up menu, it displays an error
message on the panel and moves to error state.
After moving to the error state, turning the power on/off by user operation is the only way to
return the function to the normal operating state.
Work Memory full
This error occurs when necessary memory for imaging process is exhausted. When memory
full error is detected, the function prints pages that have already been rendered and executes
the following processing.
• Regardless of [Warning display] setting in IMAGING set up menu, it displays an error
message on the panel and moves to error state.
After moving to the error state, if the job is canceled by user operation, it returns to normal,
skips importing the remaining data, and ends.
Invalid data
This error occurs when invalid data, which is impossible to be analyzed, is detected during
data analysis of JPEG or TIFF. When the direct print function detects invalid data, it prints
pages that have already been rendered and executes either of the followings. After that, if
it is possible to continue the processing, printing job of the remaining data is done. If it is
impossible to continue the processing, it skips importing the remaining data in printing job and
ends.
• If [Warning display] is set to 'ON', it displays an error message and moves to error state.
After that, if the job is cancelled by user operation, it returns to normal.
• If [Warning display] is set to 'OFF', it does neither display any message nor move to error
state.
Processing error
This error occurs when something abnormal is detected while the direct printing function
works. For example, an error that occurs when the function is importing data from receiving
buffer, or an error that occurs when the function is accessing to hard disk. When this
translator detects a processing error, it prints pages that have already been rendered and
executes the following.
• Regardless of [Warning display] setting in IMAGING set up menu, it displays an error
message on the panel and moves to error state.
After that, if the job is canceled by user operation, it returns to normal, skips importing the
remaining data, and ends.
