Checking Ink Levels for HP Photosmart C3100 All-in-One Printer Series


Use the HP software to check the estimated ink levels in the ink cartridges.

NOTE: Ink level warnings and indicators provide estimates for planning purposes only. When an indicator shows low-ink levels, consider having a replacement cartridge available to avoid possible printing delays. You do not need to replace cartridges until print quality becomes unacceptable.

Checking ink levels

Use one of the following methods to check the ink levels.

Method one: Check the ink levels from the computer using HP Solution Center

HP Solution Center is software that acts as a centralized point of access for tasks such as scanning, printing, and copying. The software is part of the software package that comes with your product. When you perform a standard installation of the HP software, HP Solution Center is automatically installed.

You must have the full-feature print driver, which includes HP Solution Center, installed to use this method. If you do not have the full-feature print driver installed on your computer, you can install it now.

Follow these steps to download and install the lasted driver for your printer.

  1. Turn on the printer.

  2. Disconnect the USB cable from the printer and the computer (if you already connected it). If the printer is connected to your network, leave it connected.

  3. Go to HP Customer Support - Software and Driver Downloads .

  4. Use one of the available methods to identify your printer model.

    The software and driver results page displays when the printer model is identified.
