Using Your Printer
Operator Panel
The Operator Panel features a touch screen for basic operations, including selecting items, scrolling through menus, and navigating the home screen. It displays information like notification bars, icons for Wi-Fi, time, and account names. You can customize the home screen by moving, adding, or deleting tiles. The keyboard allows for text input, and a number pad is available for numerical entries.
Printer Configuration Web Tool
The Dell Printer Configuration Web Tool provides access to various printer settings and functions through a web browser. You can view printer status, manage print jobs, adjust printer settings, and configure network settings. The tool also offers options for page display format and changing menu item settings.
Understanding Printer Menus
The printer menus offer extensive control over its functions. You can access reports, lists, system settings, and manage PCL and PS fonts. Specific sections cover Wi-Fi setup, paired devices, admin settings, network configuration, and maintenance. Various print, copy, scan, and fax settings are also configurable through the menus.
Troubleshooting and error codes
| Problem | Action |
|---|---|
| The scanner does not work. | Ensure that you place the document to be scanned facing down from the document glass, or facing up in the DADF. There may not be enough available memory to hold the document you want to scan. Lower the scan resolution rate and then try scanning again. Check that the USB or Ethernet cable is connected properly. Ensure that the USB or Ethernet cable is not defective. Switch the cable with a known good cable. If necessary, replace the cable. If using the network TWAIN or Windows Image Acquisition (WIA) driver, check that the Ethernet cable is connected properly and the IP address of the printer is set correctly. Check that the scanner is configured correctly. Check the application you want to use to make certain that the scanner job is being sent to the correct port. Ensure that the scanner sharing feature is disabled when you use Mac OS X before you scan documents via an ICA compatible application such as Image Capture. The printer does not support the scanner sharing feature of Mac OS X. Select a printer which is directly connected to the computer via USB or wired/wireless LAN and scan documents. |
| The printer scans very slowly. | Graphics are scanned more slowly than text when using the Scan to Email or Scan to Network Folder feature. Communication speed becomes slow in scan mode because of the large amount of memory required to analyze and reproduce the scanned image. Scanning images at a high resolution takes more time than scanning at a low resolution. |
| Document misfeeds or multiple feeds occur in the DADF. | Check whether the DADF roller assembly is installed properly. Ensure the document's paper type meets the specifications for the printer. See "Supported Paper Types" for more information. Check whether the document is properly loaded in the DADF. Ensure that the document guides are adjusted properly. Ensure that the number of document sheets do not exceed the maximum capacity of the DADF. Ensure that the document is not curled. Fan the document well before loading it in the DADF. |
| Vertical blanks or streaks appear on the output when scanned using the DADF. | Clean the DADF glass. |
| Vertical lines appear on the output when scanned using the DADF. | Clean the DADF glass. |
| A smear appears at the same location on the output when scanned using the document glass. | Clean the document glass. |
| Images are skewed. | Before loading the document(s) on the DADF, straighten the edges of the stack of the document(s). Ensure that the document is loaded straight in the DADF or on the document glass. |
| Diagonal lines appear jagged when scanned using the DADF. | If the document uses thick media, try scanning it from the document glass. |
| Message appears on your computer screen: "Device can't be set to the H/W mode you want.", "Port is being used by another program.", "Port is Disabled.", "Scanner is busy receiving or printing data. When the current job is completed, try again.", "Invalid handle.", "Scanning has failed." | There may be a copying or printing job in progress. When the current job is complete, try the job again. The selected port is currently being used. Restart your computer and try again. The cable may be improperly connected or the printer may be turned off. The scanner driver is not installed or an operating environment is not set up properly. Ensure that the port is properly connected and the printer is turned on. Then restart your computer. Check that the USB or Ethernet cable is connected properly. |
| The printer does not properly transfer scan data to a specified destination via the Scan to Email or Scan to Network Folder feature. | Check if the following settings have been set correctly on the Dell Printer Configuration Web Tool. Scan to Network Folder: Check the following settings under Address Book→ Server Address: Server Address, Share Name, Server Path, Login Name, Login Password. Scan to Email: Check the following setting under Address Book→ E-Mail Address: Address. |
