Starting around 2012, HP started releasing scanners that used the “Low End Data Model” (LEDM) for the command set. The first generation of these USB scanners used the SCL command set, which was compatible with the SCSI Scanjet scanners and was well documented. Most HP scanners after 1999 were USB 2.0 scanners. The original HP Scanjet scanners used SCSI, which uses a complicated interface card and a thick, bulky cable. Some HP scanners also have WiFi or ethernet interfaces.
Types of HP ScannersĮxcept for a few SCSI Scanjet scanners, most HP scanners are USB scanners. More than 400 models of scanners have been sold by HP since 1988. Some of the product names were Scanjet, Officejet, Deskjet, Envy, Laserjet, Pagewide, Photosmart, psc and Smart Tank. HP later started to include USB scanners in their printers, and produced a large number of stand-alone scanners as well. These were SCSI scanners that were well regarded that used the SCL (Scanner Control Language) protocol. After doing this, Scan to Computer worked! Why was this change necessary? The support person claimed it’s because of a known bug in the HP software.HP has been in the scanner business longer than any other vendor, starting with their ScanJet scanners in 1988. In particular, I needed to change the “Move Finder Items” destination folder from its default selection (Documents) to any other location (I created and selected an HP Scans folder). To fix problems with Scan to Computer’s Save as PDF task, you need to edit the relevant Scan Tasks item in HP Utility. Fixing the problem with these choices required that I edit each of the tasks. I had been unsuccessfully trying both Save as PDF and Save as JPG. This revealed a list of “shortcut” tasks with the same names as appear on the 8600’s touchscreen. Return to the Scan to Computer section of HP Utility. When he returned, he had a new tactic for me to try: After rehashing much of the same fruitless territory as covered in the Forums, the support person put me on hold. But this may not be sufficient.Īs a last resort, I telephoned HP tech support. To initiate scans directly from the printer, you first have to enable the HP Utility option shown here. While these steps are necessary, they were not sufficient to be the solution. Had I checked the “Enable Scan to Computer” option from the Scan to Computer section of the included HP Utility application? (Yes, I had). After I posted a message to the HP Support Forums, two HP employees replied with queries: Had I installed all the HP software that came with the printer? (Yes, I had).
