@robodobo Run out and get yourself a new µSD card, 8GB minimum and preferably a name brand (Sandisk, Samsung, etc) from a reputable seller. If you don't have a card reader, then get one with a USB adapter or get a USB Multi-card reader. Download Win32DiskImager (Windows), there are apps for OSX or you can also use Disk Utility to image the existing card. Open the printer's bottom door and carefully remove the µSD card and put it in your reader. Make your image or backup. Now put the new card in the reader and write that image or backup to the card. Put the new card in your printer (be mindful of the orientation), it will only slide in easily in one direction. Then button everything up and power on your printer. If the new card was 8GB then you won't need to do anything else, if you decided to increase the size (16GB, 32GB) then there will be a few additional steps involved to use all the space available. Download Putty or BitVise SSH (Windows), vSSH or maybe others (Mac OSX). Use it to connect via IP address to your Robo printer. the default username is pi (case is important) and the password is raspberry (again note all lower case). when you get a command prompt type sudo raspi-config (all lower case) the first choice should be expand filesystem. If you select that it will write some text to the screen and tell you it is going to reboot and does in about 5 seconds. After that you printer will restart and you will have extra space (16GB, 32GB depending on the size you chose). This is not an exact step by step guide but should get you up and running with a better quality µSD card than that supplied with the printer.
