Results are presented of a search for MeV-emission from Geminga using all available 0.75-30MeV data gathered by the imaging Compton telescope COMPTEL between April 1991 and September 1994. Timing analysis yields a negative result in the search for pulsed emission in the 0.75-30MeV range. A more sensitive method, which produces images for various pulsar-phase selected components and for the total emission yielded in the 3-10MeV range an indication for emission mainly coming from an interpeak component, called I2. This is the softest component observed by EGRET and COS-B and was therefore the most promising one in the COMPTEL domain. The time-averaged fluxes and 2σ upper-limits estimated for the total emission and for 4 defined phase components do not require a break in the spectra extrapolated from EGRET measurements. Spatial analysis using all available Anti-Centre data for different energy ranges reveals evidence for other sources than the Crab. This is shown for the 10-30MeV range.
