Scanning area 73
Based on these values the limits of the parameters for the esc a command are as follows 74
Based on these values you can calculate the maximum scannable area for various resolution and zoom settings according to the following formulas 74
In dots the maximum main scan value at the maximum resolution 100 zoom 74
In dots the maximum sub scan value at the maximum resolution 100 zoom 74
In dpi the maximum scannable area available 74
Main scan in dots 74
Note the limits of the 74
Parameter depend on your scanner model see your scanner s manual for details 74

After trimming an image you should resend the esc a command using the following parameters 79
Determining setting values after trimming 79
The parameters for the esc r esc h and esc a command should be set to the following 79
Image trimming 2 80
Main scan reading length inches 80
Main scan resolution dpi 80
Main scan skip length inches 80
Main scan zoom 80
Printer resolution dpi 80
Rough scanned image printing size after trimming 80
Sub scan reading length inches 80
Sub scan resolution dpi main scan horizontal 80
Sub scan skip length inches 80
Sub scan zoom sub scan vertical 80
This section explains how to use the esc r esc h and esc a commands to print a trimmed image on your printer 80
Based on the size of the image you plan to print and on the resolution of the printer use the following formulas to determine the final scanning settings 81
Determining the setting values for printing 81
Main scan zoom 81
Note on scanners that can respond to printers and other various output devices you can set the 81
Sub scan zoom 81
The parameter values for the esc r esc h and esc a commands then become as follows 81
Values to match the horizontal and vertical resolution of your target printer 81

Items not affected by function level 88
Problem the scanner does not scan correctly when a scanner with a different maximum scannable area is connected 89
Typical programming errors and solutions 89
Problem although you have attached a new scanner capable of a higher resolution you cannot achieve that resolution when scanning 90
Problem when connecting a different scanner model in your scsi daisy chain an error message such as the following appears the epson scanner is not connected 90
Problem after connecting a scanner with a higher function level than the previous scanner the new scanner does not operate properly 91
Problem the speed of image data transfer remains the same whether you use a scsi or bi directional parallel interface 91
Problem after using a scanner option automatic document feeder or transparency unit a different program attempts scanning although the second program tries to scan without using the option the option remains operational 92
Problem the scanner scans properly when you use a bi directional parallel interface but when you switch to scsi the scanner no longer operates properly 92
Problem when connecting a different scanner model a time out occurs on your computer and you can no longer scan 93
Problem when writing data from a gt 6000 or gt 4000 to a magneto optical disk an interface error occurs on the scanner 93

Data form definition commands 112
Command reference 117
Esc d and other commands 117
In the color scanning mode the data format setting defines tones for each of the three primary colors green red and blue 117
Note even when the specified values exceed the capabilities of the computer display or printer data is sent according to the specified format and quantity before scanning you should consider how the image data can be stored or processed 117
Specifying the data format determines the amount of image data in each data block 117
The data format selected by this command determines the effective halftoning mode selectable with the esc b command 117
With multilevel data settings more than 3 bits per pixel per color the halftoning modes are not effective 117
Caution the length of the m ain scan should always be specified in units of 8 dots or an integer m ultiple of 8 o therwise a com m and error occurs in the scanner 125

The extension sense data format is used for the sense data created when an error occurs this format is described below 179
This is the illegal length bit when set to 1 this bit indicates that the transfer length or assigned length specified with a command is not the same as the actual data length required by the scanner 179
When set to 0 this bit indicates that the data in the data byte is invalid when set to 1 the data is valid 179
